I'm compiling gearing info and need to know whether the Yukon's and Baldwin gears were different from the OEM. Right now I'm assuming they were the same as the later years but need to know for sure. Besides Nate McCoy's billet transmission (which I have ratios for) and Arlan's new 250R tranny gears, I don't think there are any others aftermarket manufacturers. Let me know if I'm missing one.
