488 ring and pinion 2nd gen RX7

[racecarjohn]

I went to buy a 488 ring and pinion gear for the 2nd gen RX7. Mazda Comp will sell me one but it needs to be motified to fit the 2nd gen housing. I guess you have to cut and weld on a loner shaft from a stock pinion gear:shrug:

Or does anybody know where i can buy a used one (Complete rear or the modified gear set)

isc and speedsoure said they cannot help.
Please any advice will be welcome

I have access to getting your pinion modified for the ratio you provide along with a donor pinion. I need three orders to set-up the process for the modification. PM me if you have an interest in getting it done. Turn around time is around 60 days as this is a custom-tedious process. Trying to find a bargain is out there is difficult....
