Driveshaft question

I know it sucks to wait, but it is always best to measure once the trans is in.

You're right...it sucks to wait. :) plus I have the chance to get a rebuilt 727 and pick from a small selection of driveshafts from a fellow Mopar man who is moving soon. I guess I can measure what's in it now for the shaft, do the math on the trans difference and pick one that's closest. Worst case scenario is that I have to get it modified which is the situation I have now anyway. :)
