Spent the last 4 hours or so searching, reading, following links, more searching, etc. on the subject. Just want to clear a few things up.
From this I think I can conclude that what I need to do to get dual RF1A cases beind my AX15 is to swap the tailhousing and output shaft from an R151F onto my AX15. Am I assuming this correctly? Would any of the other tramsmission tailhousings work?
Could a tailhousing housing with a forward shifter work, provided the first RF1A unit is also forward shifting? The second will need to be top shifting anyways, right?
Spline count shouldn't matter if I get the tailhousing/output shaft and transfercase from the same truck, right?
Any easy ways to ID transmissions by looking at their case?
