8 3/4 rear in 65 Signet

I don't know what year 8 3/4 you have. When I put a '71 8 3/4 into my '64 I had to reuse the parking brake cables from the old 7 1/4 rear axle. They swapped right onto the new brakes with no problems. The reason for new U bolts is because the new axle tubes are 3" (I think) in diameter & the old ones are smaller. I also have a 741 center & have never had a problem with it. The entire swap is pretty easy. Biggest hurdle is shortening the driveshaft, 2 1/4 inches if I remember right.
