correct driveshaft length

Can anyone give me the correct driveshaft length for a 67 B Body (Charger) with a 4 speed and an 8-3/4 differential??


thanks

Assuming a 383 engine, the service manual and parts book both say 52.03".

Some info here:

Thanks. It was a 383 originally, but now has a 426 Hemi in it.

I'm assuming you are searching for the correct length shaft for a bolt in deal. If your eng/trans/rear is already in I'd butt the front yoke all the way in the trans & measure C to C then subtract 3/4 to 7/8 & see how close you are to what you are considering purchasing. If you do end up having to cut one down I'd suggest shooting for an end play dimention of 3/4"-7/8" with the axle loaded not suspended. wouldn't hurt to check end play with the correct shaft installed either

Thanks Robert. I already have a shaft in there, but I think its too short. I will measure it today and see where we are. Is 3/4 to 7/8 enough end play to compensate for suspension movement? The car is totally stock underneath except for the different engine. I am positive after having the shaft out recently that there is way more than that much end play. When I bought the car years ago, the previous owner lost the original shaft, so I found this one on E-bay. It works, but I don`t think it engages the tailshaft quite enough.

Yes, it dont seem like very much but it is plenty when it comes to shaft end play. Going the other way on my dd 65 dart there was not enough yoke engagement into the trans & it would vibrate on occaision so before something fubared I changed the shaft to a slightly longer one (swapped the same front yoke) & that took care of it
