WTB Mopar 8 3/4 ring and pinion
 
Looking for a 4.71 ring and pinion for a 489 casting 8 3/4 Mopar rear end.


Thanks

I've never heard of a 4.71 ratio for 8 3/4 but I have a Richmond 4.75 for a 742 housing with about 5 runs on it that I may consider selling.

I was told 4.71; probably is a 4.75.
I use a 489 case. Thanks anyway. I'll keep looking.

I don't think any were made for the 89 housing. Jerry Stein had 50 sets made for the 42 housing almost 30 years ago and I think whatever is around from that lot is all there is.
