Driveshaft Length 1971 Four Speed Satellite

[VAD Gold Rush]

I'm gearing up to swap an A833 into my 1971 Plymouth Satellite Sebring to replace the A904. The car currently has an 8 1/4 rear. Has anyone here used the long tailshaft transmission with the 8 1/4 rear and knows the length of the driveshaft?

If nobody here knows, I'm not scared to measure. I'm just looking to save some time.

So if your not scared than measure what you have then you will know its right. You wont be saving any time with someone else's measurement that for some reason is not what you need.

Hmmmm….any plans for an 8-3/4”? I suspect the length is different and the 8-1/4” will break really quickly

Take your time and replace the rear housing THEN get a driveshaft or have one made... That rear won't last long beating on it.

I'm not looking for advice on swapping rear ends. That's not in the plans for the car. It's just a 318 car that I'm tired of pushing backwards every time I drive it. I was just curious if anyone here had concrete numbers to go by with this combination.

Then just fix the 904 seems like a lot of work to cut and weld a hump in, weld in the Z-bar frame bracket, put the pedals in, get shifter, clutch, z-bar, clutch rod, flywheel, trans, bell housing, make a driveshaft etc... "just so you have reverse".

I have all the parts I need in storage. The manual swap is happening soon. I'm using the lack of reverse as motivation to do the swap I've always wanted to do.

Nearest data I have is 57.42" however as stated numerous times, I would HIGHLY recommend that you measure it yourself.

That 8.25 might survive longer than some would think, really depends on how you drive it and what condition its in now. If you are "just driving" the car normally it should be fine for a long time. People tend to forget that the standard trans in many of these cars was a 3spd manual and the 8.25 rear-ends lived behind them for many years.

There seems to be this feeling that every vintage Mopar is a hot rod, muscle car, etc. and we forget that some people just like to drive them as typical commuter cars.

I converted a lot of cars back in the day, never regretted it.

Don't get me wrong, my car is a stripped down hot rod. That being said, I barely ever even chirp a tire. I've got a big block A body to race with. The Satellite is just a cool driver. I appreciate you giving my thread the time of day to make an actual reply.

You are very welcome. There are a lot of assumptions and preconceptions on these forums and many people answer posts not understanding the actual issue (I am guilty of this myself more than once).

I like many come to forums for answers, suggestions, etc. and too often are met with somewhat of a hostile crowd. Sometimes it is self inflicted and other times people don't know what they don't know so the questions are phrased incorrectly or strangely so the "old guys" answer sharply.

All this said, Google is your friend and if you type Mopar Drive Shaft Length Chart you will see there are several out there. Someone posted one on FABO and I extracted it for my files. I do not really trust any chart I would get off the internet or even a manual, I would want to measure it myself because there are a lot of variables and it is relatively easy to do.
