Rearend 7.25 junk????

They are good rears as long as you aren't going to beat on the car.I have a 323 7 1/4 sure grip in my 65 Valiant station wagon and it serves me well and has for the past 20 or so years I have been driving that car. In 65 that is what was used in Barracuda formula S cars and Dart GT as well.Mine came from a 65 Dart that a little old lady owned .She bought it new with a 170 slant , auto trans,and for some unknown reason a sure grip.It had 56,000 miles on it when I got it . My friend made the Dart a commando V8 car and used an 8 3/4 in it. Now that rear has well over 200,000 miles on it and works as good as the day it was built. So the rear you are buying is worth saving but if you are going to use it in a car that you are putting a bunch of horse power in you are kidding yourself .
