Al, Beginning in 1942 the pickups got an open driveline. No torque tube. But in order to address your question, the driveshaft should not need to be altered in this situation. The driveshaft I am currently running was built a year ago to accomodate a T-5 transmission from a chevy S10. This altered the length and type of yoke from stock. Now we deal with the back end. It's hard to measure how far the yoke extends forwards especially on the current stock axle. Then factor in different axle tube sizes to butt tape against. I feel quite confident I am really close to same number and of course slip yoke travel is important to keep in the zone. I won't know for certain until axle is mounted in the vehicle. Fingers are crossed on this one.
