For the front the worst part is flattening out the parking brake cable bosses on the frame as the shackle mount goes pretty much right on top of it. The rest is just drilling a few holes and lining everything up.

In the rear I used the factory 67-72 rear leaf spring mounts & parts I had from converting my stepside to trailing arm suspension. The forward mount of the rear square body stuff is all wrong and won't work well on the 67-72 frame. A 67-72 GMC will have the leaf spring stuff you need and should be fairly easy to find. The square body rear leaf forward mount was way too tall and threw the spring angle way off. Probably 8" too low. The design of it would take a whole lot of fabrication work to modify it to work in a 67-72 frame, not really worth it unless you have way more time than money. Pinion was at about a 30-degree downward angle.

I did notice that the rear leaf front mount on an 88-98 truck could be made to work. I used the Bell-Tech forward drop brackets off my 89 C1500 on my 68 C20 when I converted it to leaf spring suspension from the worn out trailing arm stuff. The stock 88-98 parts look like they could be easily modified to fit a 67-72 frame as well.
thank you that helps alot cause not to offend alot of people but they try to stay tradional and i just wanted to try to keep the ifs feature on my truck but the only way to do that is to go with a newer truck and thanks i just needed some advice well now i could go the route of converting my truck to 4x4 once i find a donar truck with ifs thats 4x4 wish me luck guys thanks for the help by giving me ideas
