Hey all,
I am a couple weeks away from really worrying about this, but I hung an A body 8 3/4 under my 66 Dart. My car was a factory V8 car but I have to be honest, I tore the original rear end out of it right away and I have no idea what it was. I did check and my original driveshafts U joint fit perfectly into the the pinion yoke on the 8 3/4. I am also staying with a 904 so I am sure that is all the same. My question is, Will I need a different length driveshaft ??
Thanks all
blackdart66, your dart might have already had a sbp 8 3/4 w/ a 741 gear
case. Anyway, here are measurements for 3 rears, 7 1/4: 10.09 centerline
of axle shaft to centerline of rear u-joint, 8 1/4 is 11.69 and 8 3/4 is 12.35.
If you knew the orig. rear you just subtract and thats how much you shorten
your d-shaft. I just did this in my 65 Valiant.
