New rear end

[73ChargerSE]

I bought an 8 3/4 rear at a junkyard for 100 bucks, Sure grip, 489.  I was planning on replacing my 8 1/4" in my Charger, but I measured the perches outside to outside and they are an inch short total on the 8 3/4".  I've already had it powder coated by my uncle, so is there a way other than relocating the spring perches to make it fit in my Charger?

I don't believe there is any other way.  I myself am right in the middle of doing the same axle swap on my 74' Charger.  Did the removal this weekend with the friend in the pic.



I did not want to have to mess with the spring perches.  So I found a donor housing from a 72' Roadrunner with the same perch locations.  From what I understand though.  Its not a big deal to have the perches moved. Other than you would have to have it powder coated again.  By the way $100.00 for a complete rearend with a suregrip.  Is a good deal.  I would find a way to make it work. Dont ask me what I am into mine.

That IS a good deal.  Is it in need of a rebuild? 

[73ChargerSE]

No, the rear end does not need a rebuild.  The thing is as tight as can be and the gears are VERY clean. There is a very very light coating of rust on the ring gear, but i'm sure that will come off after use.  The only thing is, that it is the cone type Sure-Grip.  I painted the 3rd member to what my auto teacher called "show quality".  My uncle did me a favor by painting it, so I hate to ask him to paint it again.

The '73 B body perches are  47.3" apart, the E and C body perches are 46" apart.

You might be able to find offset rear spring shackles that would bring the springs in to 46" or close to it.
