Help identifying my differential
Hello everyone, this is my first post - been reading here a lot and get most of the answers I need. This one has me stumped. My car is a 74 Duster with 727 auto and I'm trying to find the right speedo gear as my car has none and leaks a lot there. I jacked up the car, spun the wheel and counted drive shaft rotations. 2 wheel turns - 2.4 (estimated) drive shaft rotations. Wait, this doesn't line up with any gear ratios I can find on any mopar charts! So I popped off the diff cover and counted teeth, 20 to 49. That's 2.45:1. This number is also stamped on the ring gear. So, I'm assuming this is not a mopar rear end? The housing looks like a GM 10 bolt as per this thread;
Mopar Rear End need help to identify
If that's the case, and if someone can confirm that, what was all changed in order to make that work in my car... brakes, driveshaft, etc? Thanks!
