Bolt Kit

[mashud46]

Anybody ever done a complete frame off rebuild and replaced all of the bolts on the frame / suspension? Just got my chassis back from powder coat and I'm either replacing everything or restoring what I can / want to. Looking for a bolt "kit" if available or at least a list of sizes if possible. Just seeing what's out there before individually measuring and replacing them if I have to. Thanks in advance.

Most of your suspension components will come with the hardware included (control arms, sway bars, etc.). If you need body bolts they come as a kit (Kirban and others have them). Any original equipment you put back on, just clean and paint the bolts or replace with Grade 8.

If you want IMO a really nice restoration don't use the bolts that come with the kits. I call them walmart bolts generic looking stuff. Use your original stuff well cleaned blasted and coated as long as they are not severely rusted and obvious lacking strength for the job they are doing. Pick n Pulls are a great source for OEM bolts!

You can always check out this thread. It may help.

Body Bushing Bolt P/Ns for MOST G-body applications (YMMV)

I see the following posted around different places...and, well, it's partially incorrect. It won't matter if you find the GM part number bolts, as they'll be correct for the application, but if you use store boughts, you may be surprised. I have highlighted the incorrect stuff in red. Position...

There's also this, if you don't mind buying from G-body Parts:

I redid the suspensions on both of my cars. Saved one of each bolt for the front and rear suspensions. Then after I measured the length I called belmetric.com
in MA. You can buy ALL of the needed hardware from them. They carry regular hex head and also flange bolts like OEM in grade 10.9. They also sell prevailing torque lock nuts in regular hex and flange in 10.9. Do not use cheap hardware on your suspension. Also I would HIGHLY recommend not using nylock nuts.
Belmetric is fairly priced, you can purchase any amount, and they ship quickly.

I've reused all the suspension bolts, but did buy replacement body mount bolts from Fastenal.
