7 1/4 rear end 2.76 gear interchange question
« on: March 06, 2017 - 09:30:18 AM »
Well I finally got to take apart the rear end on my 318 1970 Challenger project and found the pinion and ring gears have broken teeth. No real surprise I guess. I do not want to change the rear end or change the existing ratio.  I found a set on flea-bay but I need to know if they will fit.

The ones on e-bay are:  3507747 (ring) and 3800275 (pinion).

My original ones are: 2800275 (ring) and 2800276 (pinion).

Will they fit?  If not can some please point me to a set that will ?

thanks
Chris
