1 piece drive shaft.

[Ackattack]

I want to switch to a 1 piece drive shaft for a few reasons. My question is, what drive shaft is a good candidate for this. I have a long bed, TH350. I figured that a mid-late 70s PU would work, but not 100% sure if they had single DS.

Anybody else do this, what problems did you run into?

later trucks have a 2pc,for short box,one of my trucks has a Ford van one,and the 67 GMC short bed i have came factory with one,ive also bought a few factory ones from short bed trucks in the boneyards,61-4 Impala 2 pc drivelines i found out bolt into a short truck,i needed a driveline and was into 61-4 Impalas at the time and found they fit perfect.My suggestion just go junkyarding and look in anything Ford,Chevy something the same length.But if your truck is slammed careful with your pinion angles that carrier bearing helps offset.

just assuming that a shaft iwll work from one model of vehicle to another just cuz of the model it is wil get you no where fast,
its the tape measure that will tell you if a certain shaft will work for you in a vehicle or not. there were many different wheel base lengths and drivetrain lengths made, many different shaft length made.

73-up wheelbase are 4.5" longer, auto trannies and three speed trannies increased in length by roughly 3" in 73, just for starters,..,

measure from tail enf of tranny and back to axle pinion yoke and then start measuring up some driveshafts til you find one that is length you need.
