ya'll probably already saw the pictures my little bro posted with the broken tcase. i was just looking at the different years of tcases in the tech part of this website and they all look like they will bolt up to any land cruiser tranny. am i wrong? he has an 84 fj60. there is a guy parting out a 40 in idaho falls and says that the 40 was a 3 speed. does any of that matter? what is it based on-spline count? will any tcase off of a 40,45, 55, etc bolt up? thanks for the input.
