I drew up the driveshaft maker the most perfectly clear diagram for my last build. I didn’t have a yoke (I figured they would want to choose the one for whatever joints they had) it was a normal gm 27 spline like TH350. So I couldn’t give them a u-joint center to center. But i did give them a illustration picture clearly stating from rear end flange to the tip of the output shaft was like 24”. So they made me a drive shaft that was like 2” too long. I asked the place how they thought a 26” or longer shaft would fit in between two fixed pieces 24” apart. They were like “uhhhh we can just shorten it”.

I ended up blowing it into pieces a year later anyways hahahaha. That was a loud bang.
