41-46. OK, I just lost 90% of you. For the rest- Will a four speed (we're talking a stock 41-46 4 spd tranny) bolt up to replace the standard 3 speed on a '45 1/2 ton standard wheelbase? I have heard that the bell housings were different between the two. 4 speeds were standard offerings on the long WB CC102's but not an option to my knowledge on the CC101's. Thanks for any pointers.
