Hi All, new to this forum. I just purchased a 65 Sky Convert. and am planning some running gear updates for it. I was surfing the local craigs list and found a couple of posi rear ends, one out of a 75 el camino with 3.25 ratio and another from a GN with a 3.73 ratio, both are 8.5" units. I plan on getting a 200-4r tranny. So a couple of questions:
1) which gear ratio would you all recommend for this car
2) which of these to rearends would be the easiest to install in the 65?
I don't plan on hitting the strip just want something that is nice to do some crusin around with decent performance and milage. Currently the car has a 300 in it for a motor, but that could change down the road as well.
