    Thoughts on shocks/suspension and bad roads

    All: So I live several miles out of town, and the last 1 1/2 miles is really bad washboard. I know the county can do a decent job grading it, because they've done it before, but the last time was like 5 years ago, and they haven't done a grading job that's last more than a week, since. The car...

    Cab bolts: A comedy of errors

    All: A few months ago, I got my flat dump bed going, and mounted a tray for a second battery, to the frame behind my cab. (V3500, 1989). I recently noticed that my tray was on a weird angle. I live on a really bad road, and I hadn't welded it well enough, to the c channel. I go to re-weld it...

    defrost not working

    All: The blower motor on my 89 V300 recently quit on me. I installed a new one, which works fine, but now I have no defrost. Looked through the pictures on the sticky thread for this topic, but am still not clear on how to proceed. Basically, the upper slider lever on the dash, with "OFF" on...

    hydraulic pump

    All: I've got a flatbed that will dump, on my 89 one ton. I'm finally getting around to getting the rams mounted, as originally I had to cut the old lower mounting points off in order to install the bed. So, I'm now looking at hydraulic pump units. My intention is to just get one that's...

    2 cycle gas mix ratio

    A while back, I was given a 50 cc 1978 Honda "Hobbit" moped. I just got it running. Before the "that's even worse than a Ford" pile-on starts, I'll point out that it gets about 90 mpg, haha. Anyway, it's supposed to take a 25:1 mix of gas and oil. I mixed up some 25:1, and it smokes some when...

    Help on speedometer spline

    Hi all: My son's 1975 GMC K15 needs some speedometer help. It's got a right angled gear that comes off the transmission, that's driven by the gear that comes out of the trans. These two gears appear to have been connected with some sort of spline, which was broken. The cable side of the...

    Ignition Switch

    Bit of a hail mary here, wondering if anybody's got an ignition switch that will fit a 1989 V3500. I put an aftermarket one in about a year ago, and I think it's failing already; in warm weather, the truck occasionally won't start, which was the problem I was having with my original one. Anybody...

    aftermarket steering wheel install

    All: We got a steering wheel for my son's 75 GMC. Link here, https://www.lmctruck.com/steering/steering-wheels/gm-1973-99-wood-and-leather-grained-vinyl-steering-wheels, it's the one on the far right. The kit LMC sent us didn't come with any directions, and the links on the card in the box...

    rough idle

    My son has a 75 GMC with the 350. All of a sudden, it will barely idle. Problem started shortly after it ran out of gas. We replaced the fuel filter up in the carburetor, and I went ahead an put a different fuel pump in it, too, since it wasn't very much $$. Still same problem. It starts fine...

    taillight issue on my wife's harp-mobile

    All: My wife has a 1983 volvo wagon, which I'm trying to keep on the road, since it's the only car we've got that she can get her concert harp in and out of, by herself. It's kinda on its last legs, but as long as I can make it last... Anyway, it's got a taillight out, and I'm stumped. I've...

    looking for place to buy black wheels with trim for 4wd

    All: My son and I are getting his 75 GMC k15 High sierra on the road. He like these rims: https://www.carid.com/vision-wheels/56-midway-satin-black-6070452338.html. However, I can't tell if they fit a 4wd, and I'm not having any luck finding any black rims anywhere, that have those open...

    Replacing turn signal switch in 75 High Sierra

    So it looks to me like the turn signal switch is bad, in my son's 75 GMC. You can get the signals to work briefly, by playing around with the lever, right on the edge of where it would click on, but as soon as you click it all the way, the signal won't work anymore. Seems like bad switch to me...

    fixing hood hinges

    Hi: My son and I are working on his 75 high sierra. He had the usual hood buckle, we got the LMC brackets to fix it. When we got it, the hood was sitting way too high, back by the cowl. We just got his hood back on, after painting, and his hood still wants to sit up real high, by the cowl. We...

    Looking for Wheels for my Son's Truck

    hi, all: My 16 year old son and I are just about to get his 75 GMC High Sierra back on the road. He's looking for a new set of wheels for it, something chrome would be great. The stock rims on it are really narrow, would be nice to have something 8-10" wide. You can see in the pics at the...

    Whole front clip, make me a offer

    I've got the front fenders, including the inner fenders, the radiator mount and a good hood. It's got the headlights in it. It's got the horizontal side markers, so that would be a 1980 +, I believe. I've also got a not-too terrible set of doors, came off a 1980 dually. Also a nearly new...

    Weird Electrical Problem

    I've listed this as an electrical problem, since that seems likely. So my 89 V3500 just had a complete rebuild. A machinist I know completely went through the engine, we deleted the tbi, went back to a 4bbl card, hei distrobutor, new cam, pretty much the works. I've put probably less than 1000...

    Tilt Steering Column

    My son and I are working on on his 75 High Sierra K15. Right now, we're getting ready to paint, but the steering is going to need some work, shortly, and it may need a new column, in addition to a gearbox. It's a 4 speed auto. It would be real nice to have tilt steering, as the cab is pretty...

    Thinkin about my Jetta

    All: So I've got a 2003 Jetta TDI. It's got a bit over 200,000 on it. I shelled the turbo: put a rock through my oil pan, didn't realize how bad the leak was. It was already going to need some transmission work, it's the 4 speed auto, not the manual, and I'd say there's a better than average...

    Gonna build a trailer...

    All: I chopped off the back end of a 1980 squarebody dually parts truck, gonna make a nice trailer out of it. I'm envisioning the axle location, and how much trailer would be in front of and behind, the axle. You guys got any advice there? Is there a rule of thumb for this, so I get the ideal...

    Transmission Upgrade?

    Hi all: I've just recently got my 89 V3500 back on the road. It's got the TH 400 transmission in it. 454 motor. I can't remember what the rear end gearing is (I didn't mess with it). When I discussed it with the machinist who rebuilt my engine, he didn't think I'd get more than 1 or 2 mpg...

    1980 Squarebody Dually: Pictures Added

    hey everyone, I've got a 1980 squarebody dually. If somebody wants it, it's yours, make me an offer. Here's the skinny: When I got it, it was running, and I drove it to my place about a year and a half ago or so. The guy I got it from had rear-ended somebody though, so the hood and front end...

    Replacing headlights

    hey guys, this is probably a really dumb question, but... I can't figure out how to replace the low beam headlights on my 89 v3500. I just put an aftermarket LMC grille on it. Do you actually have to remove the grill, to get the old headlight out? from the front, it looks like the headlight...
