Hey guys need some help.
I am swapping my 727 out for a 904 here shortly. Have a 69 Dart. Has ladder bar suspension, so not sure the rearend( 8:75/ 489 case) sits exactly where it would have from the factory.
Anyhow, i am hoping to do the swap all in one day for several reasons.

So my thought is to find out if i can what the measurements are supposed to be were one to order a driveshaft for my car the way it came from the factory(340/727) if somebody hopefully has them, then measure what i actually have. If they agree, the rearend is where its supposed to be.
Then knowing that, i can hopefully find measurements for a 904, and order up a driveshaft and have it on hand the day i do the swap
Make sense? If the factory 727 measurements are correct, should be fairly easy to determine what i need measurements wise for the 904. Somebody has probably already done this on here...... i hope

TIA
