It's a 383 and a Dana 60? I didn't know you could get either of those in a 73....
Pics please....

Post the VIN and the info off the fender tag and somebody here can tell you what it was originally.

I had an original 73' RR. w/factory 400 hp motor, 727, 8 3/4 3:23 sure grip. NO Dana's came in these cars or 383's in 1973. Some one's been doing some swapping in the past.

It is probably a 400 and a 9 1/4 rear.Never put Danas or 383's in passenger cars in 1973.The last year for the 383 1971 and the last year for a dana 60 in a car is 1972.

That's kinda what I thought. Although, mine has the factory 8 3/4 rear, it now sports a 440/4spd. Something else you couldn't get in '73

Dude, honestly, if I had to do it over again, I would go with a 5spd. I have done a buttload of Keisler conversions and after doing the 4spd conversion on my bird, I figured out that I could have gone with the extra gear for not a huge amount more. Don't get me wrong, I love my old school 4spd, but the smart money is on the upgrade.

Yes you could get a 440,4/speed Dana 60 in 73 and 74. The guy said he didn't know what year his 383 is and you can put any rear end in any car.
What I don't understand is why pull the engine to replace a transmission front seal? The easy way working by yourself on 73 and newer B bodies is to unload the T bars and drop the T bar crossmember, then the mount crossmember and pull the transmission. If you don't have a trans jack secure the trans to your floor jack and use it.
