I have a 54 3100 Stepside with a transplanted 283 attached to the original (to the truck) 4 speed transmission. I want to upgrade to a highway friendly rearend. I have a '69 Camaro 10 bolt posi with 2.73 gears for the replacement.
Since the current bellhousing is bolted to the stock rear motor mount locations, I figure the motor is sitting in the correct spot and at the correct height. So I figured if I used a 55 - 62 truck 4 speed transmission it is exactly like mine (including the reverse shift location).
The ditch I feel I fell into is dealing with a 2 piece driveshaft. With my planned setup, is there any other drvieshaft possibilities /configurations other than using the two piece driveshaft and only adapting the rear portion to the Camaro rearend?

Sorry for the book....but Thanks
