Any Links or sources for finding the stock R&P ratio in a '71 RT83 automatic Corona. and what axle is in there. Purchased a lowered Car with 215/50r 13's. From what I can tell this is a full 2 inches in diameter smaller than stock. Anything above 80km/h and the engine just screams. I'm wondering if a new smaller R&P can be purchased from Toyota or aftermarket??

I have a Toyota 7.5" rear axle from a '93 pickup that has been professionally shortened to fit a '69 Corona. It has the correct 4 x 4.5" lug pattern with custom axles in it. I would think that it would bolt right in to your car. I have 3.42:1 gear set for it as well as a 3.58:1 gear set if you are interested. I also have a driveshaft that mated to a w56 5 speed trans. Not sure if that would be the same length and spec as yours or not. I live in Los Angeles so you could pick it up during Toyotafest if you make the trip here.
