Not a bolt in but the width should be right and it's 8 lug. I can measure whatever you need on my 62 if it helps.

Thanks for the suggestion and the offer to measure the rear end. Parts for these trucks around here are like a needle in a haystack.

Depending on what tires and wheels you are running the '73-'87 14 bolts can work. I do make trailing arm mounts specifically for the 14 bolts should you decide to go that route.

Thanks for the information. I did read that I could use a 73-87 14 bolt and I also did read you make the parts to do this. Right now I'm running a set of factory steel wheels off a 90'ish Chevy truck. I only have about an 1.5" between the tire and inner wheel well lip on each side.
