Yeah, I found that. Getting closer, but can anybody verify spring mounting widths, etc. are the same between truck and suburban?

If their from the same body yrs yes, I put a suburban 14bolt from a early 80's in my 77 pickup, you just have to watch the housings because there is differences on the widths, and if I remember correct the suburban 14bolts are a smaller r/p diamater. I didn't run into any issues with the perches. I had more issues finding the backing plates for the front brakes because I was running the big rotor, Chevy liked to use a few variations of those also

If I remember correctly, the 6 lug 14bsf didn't start in the suburbans until 92...
