Bob- I've sold and seen installed numerous sets from the vendors you are interested in. Never had any comebacks. The critical factor is installation. Make sure they are properly shimmed and the pattern is good. Also expect new bearings and seals throughout the rest of your axle assembly if you didn't do this while your car was apart.

Since I finished my car in June I have been running the stock 2.56 rear end with RamJet 350 and 700r4 transmission and at 60 mph in lockup mode it is only turning 1,400 rpm's. Replacing the 2.56 with 3.36 will increase the rpm's to 1,840 which will make the engine run better. This car is a highway cruiser that won't see the drag strip anytime soon. I am averaging 20 mpg and hope this doesn't change much. > Bob Haggard > > >
