Ford 8 inch rearend swap

There are a lot of Mopar parts that are "in my opinion" over priced ("A" body 8 3/4 rears for example). Mopar 8 1/4 rears are more affordable, but I like being able to change rations easily. A Ford 9 inch is strong, but also a bit pricy. Since I am running less then 300 hp, the Ford 8 inch fills the bill nicely. You have to look around a little, but they are affordable. Got mine drum to drum for $100, and found a "chunk" with 4.30 gears and a mini spool for $200. And my car is not a restoration. I look for "Bang for the buck".
PS: At one time I had a 68 Merc Cougar, with a 440 Mopar , 727 trans, 9 in detroit locker. That's what I had available to work with on my budget. The only "new" parts on the car, were the reground cam and the torque converter. Ran 10.80's at 122 mph.
