Hey, there is some info I need to know on doing this HD diff to non-hd transmission. I just swapped the engine in my car to L67 and I want to know if the the Non-HD@(3.29) will be changed to (2.93) when I swap to HD. And, is that all I need to do, or do I have to go in beyond the valve body and swap other internal trans parts? BTW, i already have the axle and Torrington bearing.
