Putting in a 9 inch will require some other changes.. Driveshaft yoke needs to be changed to the 1310 Spicer style. You will need the 9 inch drums and backing plates as well. Look for a 57 to 60 rear or a early Mustang Bronco or Maverick. Possibly a Granada or a Lincoln Versailles as well. Used 3.89 or 4.11 gears should not be hard to find.. A lot of 57s had 3.89s

I have a 1956 Ford low mileage rear end if memory serves me right approx. 60,000 miles with a tag that says 3.89 and the car was an original stick shift with overdrive. The car was a wrecked 56 victoria of which I used for parts and I've had the rear end put up for well over 20 years. Don't think I'll ever use it and it is complete. I had another 56 Crown Victoria I was gonna use it in but it got sold the way it was years ago.  $200 for it but needs to be picked up it's too big for me to ship. It's always been kept in the dry. If interested you can call me at 828-298-2197

No, I didn't know that I could use a 9".  That helps a lot.

Find a 6 cyl with overdrive car..  You realize a 9 inch or 8 inch can be a bolt in?..

I have a '56 Crown Vic with 292.  It used to have an automatic but now has a Mustang 5 speed with 5th gear being a 1.25:1 overdrive.  My rear ratio is probably 3.30:1 and I would like more like 3.90 or 4.10.  Any suggestions where to start hunting?  Prefer to not purchase just a ring and pinion gear since I don't know anyone who will assemble it being this old but if I can find one, I can work from there.

I found some posts here on the subject but all pretty old..
