Where to find info on an 833

Hi, we have an 833 we bought for use on a 71 RR we're building.
Have decided to go auto.

Friend we bought it from has no idea on it's origin.

Is their a resource on line or here to determine what it is from, year, etc.?

Stenciled #s are: 4F 245825, PP8334852
Cast case #s : C99129H
Tail case #s: C99539E
23 Spline

We want to sell it and the flywheel, new clutch and bell housing to offset some of the cost of a rebuilt 727.

Thanks in advance, Joe

74 model year b/e body. Casting number on front bearing retainer?

are the stamped numbers clear? got a pic?

4F 245825 would've been a Newark, DE assembled '74 Dart or Valiant

4852 is Saturday, November 9, 1974 (too LATE for 1974 model year)

I have cast iron case NP833 23 spline I'm wondering what it came it came out of originally, it has a stamp of PP8333020 and them stamped OE125609 on the same line with 0225 stamped directly under it on the same pad. The case casting number C99129
Sorry for hijacking this

Cab like you I have 2.One is early with flange for drive shaft.The other is supposedly from 69 RR.Sat in friends building for probally 30 years.Been in my other garage for years also.Rocky

It is from a 1970 Challenger from the LA plant.

New number to me, but if the owner ever registers the car I can let you know.

Thanks, I would really appreciate the help
I was going to put a A body main shaft (out put shaft) with all the gears on it, and A body tail shaft housing on this case, not now
I don't have a 1970 and later B&E body tail shaft housing so it is time to look for one
I do have a good SO CA desert 1966 to 1969 B body tail shaft housing to trade if anyone is interested in trading

Getting back to Dan Brewer on the casting # of the front bearing retainer.
Dan the # is: 69866 and a backward "C"

Thanks, Joe

Should be C99369? They can be hard to read sometimes. With that retainer, it's 4.805" diameter. Would have come out of a 74 B body with a 400 BB.

Ha! that's funny, reading it upside-down, the numbers worked, though...LOL

Thanks, Dan
