I have a rearend for sale with the following ID info: Ring gear # 6-15-62 Dana 18426 a3d50 43-13. Backplate to back plate-49" WMS-to-WMS-58.5" Bolt patt (approx) 5 on 4.5" Also has two US Pat #'s.
When I popped to cover it looked outstanding inside. It didn't have clutch springs in the carrier (like 12 bolt chevy posi's), but both wheels turn in the same direction when either wheel is turned. I wanted to give the folks on SDC a shot at it first, before posting on ebay. I'll post pictures of the rear on my Webshot page probably tonight. Let me know if your interested. Jimmy Pictures of rear now on my website under xtra parts:
