If anyone is looking for a rearend I'm selling the rearend I had in the truck last year. Its a Dana 61 with Strange street/strip axles with c-clip eliminators, Strange spool, disc brakes, and a 3.07/1 gear. The rearend worked great for me last year but I found a GM 14 bolt with a 3.21 gear so I built that because its stronger. Everything on this Dana 61 is new. The bolt pattern is 5x4.75. This axle is drop in ready for a 67-72 C10. I talked to alot of people when building this rearend and everyone said its stronger than the Ford 9", because of the pinion size of the Ford. The pinion on the Dana 61 is bigger than the Ford.
