Yup, they are all the same or very close. Just like the stairs in your home, they are all very close, but not identical. I think Sun Valley Transmissions list all that stuff on their web page. But why not do it the easy way. Find the engine and transmission you wish to use. That is the difficult part, procuring it and transportation and install. When you are all finished and don't like the performance or you might feel it could be enhanced, then look around for the differential set up or wheel and tire set up that would give you the change you desire. That is pretty easy as compared to the engine and transmission.
