    Sway

    I am beginning to reassemble my 78 C15. It came with manual steering and breaks. I did not tear down the front end myself. I noticed the lack of a sway bar or stabilizer bar. Is this normal for manual steering or is it just that it is missing?

    4 Link coil over talk!

    What coilovers did you end up getting? I am at that point on my build. I installed a 4-link and am moving the gas tank to the rear. All I can come up with from the internet so far is 12" with 5" travel and 230lb coils. Mine is factory ride height. 78GMC C15

    1987 R10 - QA1 Rear Coil Over Conversion Kit

    Any advice as to what coil overs to run. Looking like 12" at ride height with 5" of travel to bump stops. I am moving the fuel tank to the rear. 78 K15 short bed, step side. Mostly trying to find out what weight spring. 230lbs sound about right?

    3 on the tree

    I am looking at one now, actually. It is pre 1988 from a 4x2. Looks like 10 spline. Have to do some research about bell housing, yoke and clutch compatibility. I have an 11" clutch from the old one.

    Even the Dearborn would not hold up for this project. I have tugged on a lot of threads and keep coming up with the same answers. I was considering the SM465 but that granny gear has me on the fence. This is not a 4x4. I could just run 2nd - 4th but can't make up my mind. It would definitely...

    3 on the tree

    Okay, so I was focused on the, "frame off" portion of your comment. The restoration part was not a factor to me. I am not sure I even mentioned the word restoration. I believe I simply said resto. So, thank you for publicly explaining what the word, "restoration" means like I am an idiot. I...

    3 on the tree

    Great info / suggestions. I am currently looking at the T56 or TKO / TKX. I am not building just to break. Now I am down another rabbit hole. I can find used T56 out of corvettes but, that comes with a whole different set of issues. Anyway, I'll get there. Thanks again!

    3 on the tree

    I am under the impression that it was never going to last. I must admit, I do not know what a 30TT is. If it is like the one that came in the truck, I already resigned to get rid of it for the Muncie HD (M13). However, I get mixed responses as to the likelihood of that one standing up as well.

    3 on the tree

    This is mostly to see what opinions are out there. I am doing a frame up resto on a 78 GMC c15. I already have a 427 pushing 555hp. I want to keep the 3 on the tree because, I'm weird, I guess. Dearborn, M13 seems to be the only valid option. I do not yet know what rear gears I am going to run...

    1987 R10 - QA1 Rear Coil Over Conversion Kit

    This is why I joined! Thank you, guys, very much! You all confirmed what I had already assumed but, you gave me some really good leads to follow up on. I should have it down to the chassis this weekend. I will show my progress as it happens. Thanks again!

    1987 R10 - QA1 Rear Coil Over Conversion Kit

    I am very interested in a 4 link or coil over kit for my 78. Everything I found will lower the truck. I am a little too old school to appreciate the whole dropped with 24's genre. I want the performance at close to factory ride height. Does anybody have any suggestions?

    New guy here!

    Also new here, from PA. Have had a 78 GMC step side for quite a while now. I finally got the opportunity to start working on it. It's pretty rough body wise but the frame is nice. I am excited to share the progress and get ideas and info from some of you. Forgive me, I was watching a lot of...
