Sorry John.. I have to disagree with you.
I have a 1998 4L60E from a Bravada in my truck right now... with the stock transfer case bolted to it... so you are right.. it will bolt together.
But.. the transfer case is clocked about 5 degrees clockwise from where the stock one is and this makes the propshaft hit the floor of the truck.
It does bolt right up though.. starter fits too... with the tranny and the motor in place.. I know someone was saying theirs would not fit with the stock tranny.
Thanks... I guess I will have to make an adapter.. off to the CMM
