    If it is a 9 inch, it is probably a small bearing, 28 spline axle version. You can tell because of the tapered axle housing.

    This is on a car I might buy and the guy said it has a 9 inch but I know a lot of people see the round pumpkin and assume it's a 9. A big selling point to me was the 9 inch rear but if it's not a 9 I might low ball him.

    Well if I buy this car then I guess I will have to put a 9inch in it down the road. This 8inch won't hold up to a 408.

    Mine is a 66. It's one inch wider per side.. I run late model Mustang wheels and it's a perfect fit.. if u wanna Retain original width have the longer side cut down. It comes with trac lok 31 spline and 373 gears and disc brakes so it's a bargain at under 200$ the old leaf perches need to b cut off and new ones welded in correct spot.. it's really ez and will take 400-500 HP + on slicks all day long

    Just got an 8.8 that will be going in mine someday. 3.73 gears with trac-loc and disk brakes. 100 bucks. How can you go wrong. Also got the driveshaft for 75 bucks. Don't know if I will use it yet though.

    in a 65-66 1 inch wider on each side is a lot they already have a small wheel area an inch more and tires will be a problem. using an 8.8 i would narrow it
