7 1/4 to 8 3/4 Newb Questions

So.. I checked the driveshafts.

Rusty Rat Rod and 19Dart66 are correct.

Although I don't have the driveshaft I used with the 7 1/4 rear end , just the shaft for the 904 and the 727, I can see the difference right away. ( Major egg on face !!! LOL !!)

"... the correct and bestest way to do it is to measure with the new rear end installed and talk to the driveline shop doing the work and ask them how they want it measured..."

I'll just go stand in the corner now....
