Rear Diff Questions. 73 Cadillac Fleetwood.
 

Hello. I have a 1973 Cadillac Fleetwood, 7.7L, RWD...

My rear diff is shot and I'm looking to replace the ring and pinion, side gears and I will need a complete seal and bearing kit for it. Trying to find this is a lot harder than I thought. So far I've had no luck. I've got the diff torn apart on a lift and no parts to put in it. I'm looking to find out what diff came stock in my 73 Cadillac Fleetwood and if anyone knows where I can find these parts.

Also, I would like to change the ratio slightly so I have more power off the line. The current ratio is 2.93 ... Is this possible or what are my options?

Please let me know!

Thanks!
