Do both the small block turbo 350 transmission and big block turbo 400 transmission LWB C10 2WD trucks have the split two piece drive shaft?

The TH400 will be a fixed yoke on the output and the front portion of the shaft will be shorter than a TH350. I'm not certain if a TH350 2WD two-piece has a fixed yoke or not. Maybe some of these other guys will know.

So you are saying both the TH350 and TH400 LWB trucks use a two-piece driveshaft!!?? Ill crawl under my TH350 tomorrow and see if it is a fixed yoke.

The 2WD can have 2 piece shafts unless it's a TH350 long tail or 700R4.
