Slowlearn, if you want more information on the S-10 swap you need to check out jeffs51chevy build thread. This guy knows his stuff and to be honest I’m pretty much copying him for the most part. Here is his link
http://67-72chevytrucks.com/vboard/s...d.php?t=294539. I can get you the measurements you want I just need to know exactly what you want. For example outside tire to outside tire, rotor to rotor, etc… As for spacers I’m not 100% sure yet according to AD Engineering they say so, so that is what I’m planning for.
Bjcaldwe, I sure wish I could help you I’m in the same boat as you are. The entire front end was torn apart when I got my truck. Shoot I don’t even know what parts I’m missing yet. I do know I need a GMC radiator support so if anyone knows where I can get one please pass that information along. Everyone in the catalogs say for Chevy only.
I hope that helped guys if not sorry.
