    3/4 ton axles

    Yes, the lighter duty front axle K20 is the EXACTLY same as a standard K10 axle. The only difference being two (2) additional studs on the rotor. The backing plates, calipers, pads, backing plate, disk dia, bearings, seals etc is EXACTLY the same and interchangeable. There are some higher...

    3/4 ton axles

    The 3/4 and 1/2 ton axles up front (corp 10 bolt) are identical internally, the only diff is the hub (8 vs 6 lug). Most 3/4 front disks are the same as 1/2 tons, the exception is that 3/4's with higher GVWR do have the larger disks. On the rear, things are different on 3/4's. Having either...

    Vapor lock

    Used to have lots of problems in the spring, most likely caused in part by winter blend fuel being used in hot spring weather. Added heat shields to fuel lines and installed factory cold air intake. No more probs to date.

    2 Buck Electronics Upgrade

    Have been spoiled by new vehicles with electronically controlled headlamps, turn signal indicators along with everything else control modules can do. Use my square for trailer pulling, quite often in heavy traffic. Run headlights during the day / use signals often for a margin of safety...

    Painting my wheels

    x2 on the Self Etching primer. Home Depot carries Rust-Oleum SE primer, price is good, easy to apply, sticks well; used it on a set of OEM wheels 2 years ago which are holding up great.

    Turn signal fuze blowing

    Rag should be stuffed in horn to keep sanity. Watching a lamp while keeping an eye on wires as they are manipulated is difficult. Low impedance load, as opposed to piezoelectric key-in buzzers, works well in diagnosing intermittent issues.

    Turn signal fuze blowing

    Best way to troubleshoot steady or intermittent 12V short is via insertion of horn in place of fuse w/ male spade connectors. With that and a schematic, start isolating as stated above, you will have it figured out soon.

    Junk yard parts to pick

    K20 axles w/ posi. Any ratio higher than 3.08 would be helpful. And make a list of "little chrome pieces, misc stuff" broke out of your truck. When wandering the pic-n-pull yard it is not always easy to remember all the little things that you could use.

    Edelbrock clearance issues. (or go back to quadrajet)

    GM C channel frame -> Boxed frame

    Seriously thinking about buying a newer model GM 3/4 or 1 ton LWB standard cab 4x4 and cutting down to accept SWB bed. Would like to stay w/ C channel frame for ease of fabrication. Does anyone know the model year GM went to fully boxed frames for these pickups?

    Soldering equipment....one better than another?

    If your soldering on a commercial volume basis, the high dollar equipment makes things much easier and is worth the money. For learning or doing periodic repairs simple HF equipment will fill the bill.

    How screwed am I? Broken intake manifold bolt hole in head.

    Many years ago I drilled down into the water jacket of a running Cooper LM-9, never shut it down, just applied some extra silicone and its still going strong. At this point you are definitely at a crossroads. I would suggest consider drilling down with the proper dia drill till you either...

    How screwed am I? Broken intake manifold bolt hole in head.

    Is there a bolt broke off in the hole? Or did the head casting simply crumble? Kind of hard to tell with the photo.. ^^ got it

    Toyota 3FGC Forklift

    Bought a mid 80's period correct 3000# capacity Toyota forklift to work alongside my square, model 42-3FGC15. It is a great little lift, powered by the time tested Toyota 5R engine. Only thing is I have had a struggle finding technical/repair/parts information. Hence I have created a page...

    T/L CTSY fuse keeps blowing

    If you have a short that is blowing fuses, the easiest/cheapest way to troubleshoot is to stop blowing fuses. Place an old car horn, using a wire harness w/ male spade connectors in place of the fuse. (stuff rags in horn to save hearing) Move things around on the suspect wiring till fixed...

    Leaf springs - long bed vs. short bed

    I have a K10 SWB and installed K20 axles, brakes, shocks & wheels. Put K20 springs up front. Kept the K10 rear springs since the K20's were too stiff. Added 4 1/2" bump stops over the rear axle to keep the K10 springs from bottoming out and tearing stuff up when heavily loaded...

    Auto to manual hubs

    There is a special purpose socket for that, called a Spindle nut socket. Has 4 ears on it, does not fit anything but spindle nuts..

    Auto to manual hubs

    Warn or Milemarkers will drop right in once you pull all of auto locking hub parts out. Stock GM hubs should fit right in. Your existing spindle nuts should work fine, I'd leave them in. Some folks still use the auto hubs, you may find a home for those parts on ebay. pro tip #138 - Bend a small...

    Leak in steering

    Let us know how it goes! I have a good friend who owns a local shop who strongly suggested that I avoid trying to seal up Saginaw boxes on my own. He regularly re-seals some Ford boxes but not the saginaw. Of course anything is possible with some effort. The bummer would be installing in...

    Quick (and hopefully easy) question

    The answer is easy, if you can remember this simple logic: Yellow is for the lefties. (left turn/brake filament) Green is always right. (right turn/brake filament) Brown is for everybody. (parking lights) Your black is ground. White is usually ground on trailers.. Works on all trailer wiring...

    Reman power steering box

    +2 Lots of the "rebuilt" stuff coming out of the big box auto parts stores is total junk. Would guess that is the case of Smitch320. I keep all my receipts when buying anything nowadays. Would sooner trust a half wore out 20 year old OEM part over most of the rebuilt and/or chinese-taiwanese...

    Failed O'Reilly Fuel Filters

    Delivered 2 tons of Sewer-Savers to the city of Galveston yesterday. On the way back w/ empty trailer the engine power dropped way down, 30 mph max. Barely got back to shop, popped the hood and found both O'Reilly inline fuel filters had failed, dumping almost 1 years worth of trash into...
