    What did you end up doing for the front crossmember for the blazer tank? I have a 31 gallon tank I'm putting in and I got both front and rear crossmembers with the tank. The part of the frame that the front crossmember bolts to on the blazer frame must be flat though and on my K25 frame it is raised up quite a bit. I'm thinking I might just cut a slot in the brackets for the frame to slide through and then just have spacers on the top and bottom of the bracket where the bolts will go through to the frame....

    That's a nice looking rear end, I hope @Rusty Nail enjoys it. Maybe my rear end will look that good LOL. I came really close to pulling the trigger on doing a rear tank on my truck. My truck was a factory single tank, and had developed a leak. I was not happy with one 20 gallon tank, I mean unless you hammer the tank on E there is what about 15 usable gallons. That's something like 200 miles on a good day on the highway and less than 150 on a bad day with a loaded trailer even less WTF. Not ok when making a couple hundred mile journey for feed. In the end I decided to add a second 20 gallon side saddle tank. Main reasons were I felt that the two side saddle tanks spread the weight out better, it was an simpler install, and nets me a total of 40 gallons. I start with two full tanks hammering the left tank on E knowing that the right is full, plus run that to a 1/4 I've got a solid 35 usable gallons. That's 490 miles on a good day 350 on a bad day. I'm not disparaging the the rear tank swap at all I came close it and there are good reasons for doing it, I just thought I'd through out my decision making process on that if anyone found it interesting.

    Yep i understand your thinking. I too had dual tanks on a previous square i had in Canada. I was able to go down and back up Vancouver island with out refueling.

    The reasons for THIS rear tank was, as the truck will be empty most of the time 31 gals of gas is always better over the rear axle, makes the springs work a little, not that a couple hundred pounds of gas is gonna make the springs work much, but better than nothing. That and a bit safer than the saddle tanks.

    I did think the added weight at the very rear would be great for snow and ice, I considered making it a three tank setup, but didn't think I'd ever need 71 gallons on board, plus that's something like a $200 fill up.....

    200 bucks of gas!
    Hey, with 3 tanks and 71 gals of gas you could add a hand pump and sell some at a profit!

    I removed my dual 20 gallon tanks to go to the 31 Gallon tank. The reasons for this were to get the single baffled 87 Blazer tank for the EFI conversion and because I needed to move the front rear spring hangers forward 4 inches to fit the GMT-400 60" rear springs. It will also give me room to level the floor in the cab to mount newer style GM truck bucket seats.

    71 gallons of gas would also give 850 miles of driving at 12 miles per gallon without a fill up! I live way out of town, there was one year about 10 years ago where we had an ice storm and the trees that came down, kept us from even being able to get into town for 5 days and it was 12 before we got power back. For those first 5 days I emptied my gas cans, the RV's gas tank, and the wife's car to run the generator, but didn't want to empty the truck or Jeep cause we figured those would be the most likely to be used during that period. So believe me I understand the value of a fuel reserve.

    Those are all darn good reasons!

    Ha! That was our first winter here. That summer before, the wife called me dumb for buying a generator!
    I’d seen every house we looked at to buy had a generator hookup wired in. Figured it wasn’t an architectural feature, lol.
    Plus I grew up in the Midwest. Lots of trees too, but the power companies always kept them cut back from power lines. And if they were your trees they got cut whether you liked it or not.
    I noticed the libtard hippies here apparently allow the trees to grow thru the power lines. Idk why they even use power poles. Could string most of the lines to the hazard trees hanging over them!

    Well wife didn’t think I was so dumb when that ice storm hit!
    Except I ran out of siphon-able gas after 2 days. Drove down closed hwy 18 dodging downed trees until I found a gas station with power down in Tacoma.

    I think a lot of what you see is that in the old day General Electric did not bury anything. I know someone that is a lineman for Puget Sound Energy and worked for General Electric previously, I do not think that the trees growing though the powerlines is because of "libtard hippies" it's from lack of maintenance. The same reason that practically every storm we have here PSE has to borrow lineman from other companies often brought in from out of state. I don't know how they think that's a good business system, but it's just another big company trying to save money at the expense of their customers. It's not like we can switch power companies, so we are stuck buying from them.

    ^So why don’t they keep up with the trees in problem areas?
    I’m in heavy highway construction and nothing gets undergrounded unless it’s a new distribution or service line or part of an infrastructure upgrade. There will be 1000s of miles of overhead lines for many years to come.
    That said, you can’t cut a damn thing down (in construction) without ridiculous replacement criteria, IF it actually is allowed in the first place. It ain’t just due to old services , it’s due to the legislature. Aka libtards…

    It’s less costly to cut trees on straight time than work emergencies through the night
    Sorry not about 14 bolt axles lol.

    I really have no idea. I'm only talking from bits a pieces I get from my friend. He tells me about, and I remember back in the GE days the crews coming out to trim trees and they would scalp any tree with branches on or near their lines. Now he tells me it's done much more limitedly. No idea on what if any type of permitting they have to go though to do it. I do know that they cannot cut a tree down that is on private property, hence when they do it they scalp the side of the tree facing the lines. Obviously that does not stop the tree from coming down, but eliminates damage from branches. He tells me PSE has fewer lineman an hires out for tree trimming now, then when it was GE and GE had an in house tree crew. I assumed it was cost cutting, obviously I'm aware flying in crews costs a bundle of money, but more than having a full time larger staff. I don't know.

    I'm still working on the axle thing. I need to order something for somewhere just had a lot going on and haven't done it. No problem on the side topic. While I'll admit I found it annoying when I first was here as I've gotten to know folks better around here I enjoy it very much. I understand this is much more than a forum, more like a community.

    ^Ya I’m as guilty as any for off topic.
    Have you found an axle yet?
    What gearing?

    I can go down a rabbit hole with this if you want lol. 4.10 is more common in wrecking yards and easier to order with more choices. 4.56 a little harder, but they are out there. I like the idea of a 4.56 to help the 305 out as much as possible, especially with our hills and passes, but it also limits top speed in a 3rd gear loaded / towing scenario. @62 I'd be turning 3,000RPM which is about as high an RPM as I'd want to run for extended period on the highway. 4.10 would make 68mph 3K. I normally like to tow between 60 - 65max. So for that reason I like the 4.10, I like the 4.56 for knowing it'll help out more on hills. Would be nice to try both, but that's not going to happen. Obviously with the 700R4 unloaded I can hit overdrive and no issues with top speed with either ratio. I need to sit down and decide which one to get and then order one.

    Short answer I'm still pissing around lol
