Drive Shaft length - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well I am still working on the front end rebuild on my 71 SWB truck frame.
I am about ready to instal the engine and transmission.
So, I got to looking at the rest of the driveline.
I notice that the drive shaft SHOULD be a real short shaft from the trans to the carrier bearing location, due to the location of the trailing arm mounts and the trans crossmember, as compared to my LWB.

My question is:
the length of the drive shaft for a SWB from the top of the training arms (or where the carrier bearing would be), down to the diff, is the same as the length for shaft for the LWB?

So theoretically, I could swap out the shaft from the Carier Bearing to Diff from the other truck, and just get a short shaft from the trans to the CB?

Well after looking at the underneath side of a SWB I noticed there in NOT a carrier bearing.
The drive shaft goes straight from the tranny to the diff.
So, is the shaft the same lenght as the LWB or is it entirely different?

Entirely different. Someone has changed your 2 piece shaft out for a 1 piece shaft. Works well on SW trucks.
