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. | | |

I'm not one 'who really knows sh--' but I do have a 45 4-speed bolted to a 235 setting in the corner of my garage. If you'd like I could pull them apart and take some measurements for you.

I don't think you'll have a problem. As far as I know all the 41-46 pickups had the same bell housing. It should bolt right up. There was a difference in the u-joints however, but if you have a whole u-joint to go with your 3spd you're in like Flyn.
Good Luck

I have a 1955 3200 with a 235 and the 3 speed, but if a 4 speed would bolt in I would love that extra gear (plus a floor-shift )
