    Bed tail pan replacement

    I bought a new to me bed yesterday. I ended up having to drive to the other end of the state for it but in western Pennsylvania, it's hard to find a bed that isn't completely rotted. All it needs is wheel well replacement panels and, from what I understand, a bed tail pan. I need the whole...

    Rough Country lift update

    Just wanted to give an update. I went ahead and went the cheapo way since I already had them anyways. Blocks in the rear. I bought an add a leaf for each side and while disconnecting the passenger side I found that the spring second from the bottom was broke in three places. Not new breaks...

    Rough country 4 inch lift question

    Hey guys haven't posted in awhile. I'm in the process of lifting my 78 k10 4 inches. I have the front end complete. I was told that to make my truck sit right with the blocks I got for the rear, I'm gonna need an add a leaf. Just curious if anyone else has the same lift and if their truck sat...

    Plum Crazy K10

    Figured I'd give an update on my truck since the only time I posted anything was questions to problems lol. I picked the truck up for $500 off a relative who bought it and lost interest. At first glance I noticed it definitely needed inner fenders and a new core supoort as they were shot. Plus...

    Truck doesn't run right in drive

    Well I just had my rear main seal changed, my flexplate replaced because it had a crack in it, and my intake manifold gasket (and apparently missing bolts in the back replaced) and valve cover gaskets replaced. I don't have a garage or the equipment needed to change a rear main seal or a...

    No power up hill or after 45 MPH

    I'm trying to figure out why after about 45 mph (give or take) or even at a slight grade, I struggle to keep moving. Even on a flat grade, I have the pedal floored and I can barely make 55. I just change my plugs and wires, my fuel filter. And yes it is installed the right way. I'm thinking it's...

    Turn sign issue

    Anyone know why my left side turn signal won't work at the front of the truck when I turn my lights on? And when I turn my right side signal on, the back marker light turns off. Everything works fine till I turn my lights on. Like I said, it's only the left side. It sounds like something is...

    Not sure where oil is leaking

    I just noticed a motor oil leak I have dripping right in front of the tranny pan on both sides. the truck doesn't have a flexplate cover on it so I'm not sure if it's running down the block from the black of my valve covers, where I can't see, or maybe I picked up the wrong oil filter by...

    Under the grill trim piece

    Good afternoon guys. I was wondering if anyone knew what this piece is called. It goes under the grille and attaches to the fenders on each side with two bolts. Mine was already broke when I took it off and I wasn't sure what it's called to look for a new one. Thanks in advance

    Single headlight to dual headlight conversion

    Hey guys, I'm switching from the single headlights to the dual and I was curious if the headlight buckets and headlights are the same size as the single headlight or if they're smaller. My adjustment screws in buckets just won't seem to match up right with the clips. My guess is because they're...

    Not sure which core support to buy

    Hi guys. Wasn't sure where to put this question so I hope this is the right place. The previous owner let this truck sit in a field and that ended up rotting most of the bottom of my core support. The truck is a 78 but it's got an 81ish I believe front clip. So would I need to buy a core support...

    1978 K10 Pitman Arm

    Hi guys, new to the forum and to Chevy square body trucks. I just got my truck a couple weeks ago and the teeth in the pitman arm are stripped out. So long story short, I need a pitman arm. Anyone know where I can find one? Junk yards won't sell me just the arm without the whole steering box and...
