Re: Correct TH400?

I wonder when they went to the one piece driveshaft? I had several 2 piece drive shafts on lwb trucks. I figured they used long tailshaft trannys with one piece driveshafts. I'm pretty sure my 77 lwb has a one piece with a short shaft th350 though. Hard to figure the logic of it and my memory is fading. I thought the th375 was discontinued in the late 70's. The pics sweet K30 posted look like what I would expect from GM; long tailshaft with a one piece shaft.
