We moved the spring pockets in on the 57 were doing so it can run a 315 tire. Put the pockets right in the frame, worked slick, It was a easy job.

to fit a 315 you have to mini tub it right?
i was thinking about doing a leaf spring relocation kit but im not sure if i really want to cut my frame to do it. plus we dont own a welder and i took a welding class this summer with the 4-h and i did ok for my first time. my dad is a diesel mechanic and can weld though he hasnt done it in a few years, so i havent decided yet. though last nite i was thinking about maybe just going with some 16x8 on 235/50 front and 255/50 in the back. so i need to decide

Cool car!! My dad had a few while I was growing up!

I believe you can run a 285 tire with no mods...Frank would know...

what is the biggest wheel and tire combo you can run with stock back suspension frank?
and what is the biggest combo you can run with the spring pockets
