    Restoring old family truck

    I agree. My dad bought an old 65 Suburban back in 1976 and it had the 292. Unfortunately he decided to upgrade to a V-8. When I bought the 'burb, I wished it had the old 6 still in it

    ac control vacume line source

    Sorry to jump in here, but is there a diagram like the one above for an 84 Sierra, base model, 350/TH400 with AC? Or is this diagram pretty much the same for all models with the exception of trans type?

    Defroster not working

    My truck does have AC but it has been out since I removed the compressor, accumulator etc to give the engine a really good degreasing in 2019. Defrosters used to work but not since I last tried them about a month or so ago. When I go through al the settings on the control panel, the only place...

    Vent window adjustment?

    Farther down on this post, it was said that only 79-80 models had the secondary seal on the doors? Just wondering why on just these 2 years?

    Defroster not working

    I'm having a problem with my defrosters. When I put the blower on, the air is only coming out of the larger door in the ductwork near the floor(1st pic).I cant tell if there is anything missing from the vacuum connection on the back of the control panel so maybe someone here can see anything...

    Taillight lens

    I use Turtle Wax on mine, inside and out once a month, atleast the outside. Mine were faded and I also replaced both inner housings for the bulbs. They make them in black, so I painted them gloss white then waxed them. Made a world of difference

    Removing dent without backside access

    I have a similar issue on the roof of my truck. I may see if one of those places that does paintless dent removal can get it out

    Fix Slamming Doors - Striker Door Latch Repair

    That's what I used, except mine is blue to match the interior, lol. Put it on several years ago and doors close great. No need to buy the whole striker unless yours is rusted or damaged. I bought a 1 foot piece and it will last me forever. If anyone local to me has a need for some, during our...

    Upper door weatherstrip question.

    I recently saw a picture or a post somewhere, I can't remember of an 81-87 pickup with weatherstrip along the top of the door as well as around the door frame. Were there some models that had this? If so, how would I know if my 84 C2500 base would have had it? Thanks and hope you're all having a...

    Underside of hood coating ideas?

    Back in the 90's, my best friend had a bedliner business, and I had him spray the underside of the hood of my 65 Suburban(gloss black). Yes it added weight, but it looked killer and sounded very solid. I also had him do the gas tank on my original 65 Chevy II Nova 4 door. Rocks were always...

    What have you done to your square lately??

    Going to replace all the steel brake lines on my 84 Sierra 2500 daily driver. I cant get the front rubber line off as it's pretty well stuck so might as well replace it all. Got all 4 pieces at inlinetube.com for under $100

    What have you done to your square lately??

    Just about where I put mine only to the left more. Bad idea. I can't see it. Looked great as I was leaning over installing it though, lol

    What have you done to your square lately??

    My wife had a knee revision in Flagstaff June 27th but for a couple of months before we were driving I-17 from Cottonwood to Flagstaff for pre op appointments and 17 South was really bad as they were working on it. People including trucks were driving on the right shoulder to avoid the huge...

    Whats you gas mileage on your squarebody truck?

    I get about 8! I replaced the vacuum lines, has a new distributor, carb in 2019, and getting new plugs and wires. Runs smooth at idle, but under a load, it feels like it's missing. Sending it in to the shop in a couple weeks to have it all checked out

    Starter wires near exhaust manifold

    Does anyone have a picture of the tube that was mentioned? I never knew there was such a thing. Mine is long gone as I have an aftermarket 350 in my 84 Sierra

    Spark plug wires

    I have a drawing of the routing out of my 84 shop manual. I'll look at it and see how they were routed. I don't have any holders either, and want the cleanest look I can get.

    Spark plug wires

    Do you get a pretty good fit with them? I looked those up just now, and even after entering my vehicle info all the sites show are for 1999 and up. Do you have a part number? Thanks

    Spark plug wires

    I have a new distributor, and the it doesn't have the cover ring. My old one didn't either

    Spark plug wires

    What can you all recommend for a factory fit set of wires for a 350? The set I got from Autozone are definitely universal. Some are very long and some are short. I need something that fit the way they are supposed to. I would prefer pre made but if need be, a set I can cut and put boots and ends...

    Cab roof lights

    Update: Went to my local auto electric shop and he told me to use a butt connector on the end, then strip some of the coating from the feeder wire where the lights are. Did that, wrapped the light wire around the stripped feeder wire and taped them as he said. Got them hooked up and working. Got...

    Which is the correct seatbelt?

    I have a question for everyone. My 84 Sierra has had these 2 different styles of seatbelts in it since I bought it in 2019. Which is the correct one? The plastic buckle or the metal? Thanks
