I have a stock Chevy 54 Sedan Delivery. 3 spd stock trans and rear are badly worn. Rather than rebuild, I bought a 5 spd trans and 4X4 rear end (3.42) from a S10. Hope to get better hwy driving. Question is: When converting from the closed driveshaft to open, what driveshaft did you use? The S10 driveshafts are two piece with a solid mounted center bearing. Don't really want to fab up a mount for the bearing. Any recommendations well accepted.
