Will a 8.25 rear from a 76 Dart bolt into a 72 Dart Swinger?

Also will 7.25 Parts from a 73 Dart, like brakes and backing plates, swap onto the 8.25 from a 76 Dart?

Also, I read somewhere that 8.25 rears with 2.45 gears had a different case where the gearing cant be changed, Is this true?

Here is the article, http://www.dippy.org/forum2/index.php?topic=75.0

Thanks,

I'm not 100% positive about the gear swap but I think it's true.

The axle swap will require larger u-bolts and shock plates and the driveshaft will have to be shortened. Naturally, you'll need different wheels also.

I,ve read about guys drilling a 5th hole in the 7.25 backing plates(only 4 holes),so they can be used on 8 1/4,8 3/4.Do some searching in the drivetrain forums.good luck.

fishy as usual was right on...

and yes the 2.20 and 2.45 cased 8.25 are a one gear only case... you have to buy one with 2.94 and up ratio in order to be able to swap them...

thanks for the help everyone!

Yes the case is a little different but it doesn't mean you can't swap gears in it. The pinion gear on the 2.45 gear set is huge so those rears needed extra room where the pinion gear sits. You can put numerically higher gears in that housing but you will also have to swap the carrier out because it only fits the 2.45 and 2.21 ring gear.
Also your drive shaft is going to be about an inch too long if your swapping out a 7.25 rear for an 8.25.
