I've got a 76 lwb that had a 3spd and I am thinking about putting a th350 in. I've got a long tailshaft 350 out of a 78 lwb. i measured both trans and the 350 was about 3 in longer i think. anyway i know they are different lengths. the driveshaft is gone out of the 78, so can i go to the junkyard and get the first section of an auto driveshaft or do i need the whole driveshaft or can i use a shortshaft trans with my manual driveshaft?

I did that very same swap in a 79 I had. The truck I got the trans out of was a 78 and it had a single piece drive shaft as opposed to the 2 piece with carrier bearing in the 79. Everything bolted up fine and I was on my way. I had to tweek the exhaust pipe because it rubbed with the single piece shaft but no biggie.
