I believe it is a 7 1/2 inch. Is that the right term. Anyway as I said the car was built in Mexico and it has some weird bearing sizes that are hard to get. I had it rebuilt once and the diff gears were fine but the bearings were shot and my mech had a hard time finding the right size. I also noticed that it looks like the axel was cut to fit the car. Bad welding on both sides of the wheel shafts by the diff housing. It's junk! I love driving the car but with me getting older, spending money and my wife bitching at me it's time to sell.
