I bought a 86 b2000 that got hit on the side pretty bad and I plan on fixing it but I don’t know much about these kinds of old components.
the transmission and engine are appear to be in good condition but it also looks like the driveshaft popped out of the transmission I’m not sure if I can just replace pop it back in or if I need to buy a new driveshaft and install it. Help pls

 

Check your driveshaft for straightness......if it is not bent in any way, and the tail shaft of the trans has not suffered any damage, reinstall it and see how everything works. If you have some shaking going on when you're traveling down the road, then you might have some issues with it!
Welcome to the forum also.

 

Thanks I will try that
