Will this fit into the 8 1/4 in my Duster?

hi ken, what gear ratio is in your 8.25 now? that will tell us which carrier/ring gear height you need. 2.56 and up or 2.56 and down. do you need or want the 3.55s? $300 plus $50 for shipping isn't a good deal for a used trac-lok. ronnie

hi ken, check out ebay 152677572889 . brand new. see what I mean. check with cass at doctordiff.com for a better price also. you need dana spicer #75101X. ronnie

Gears are 2.45. 318/904 in the car. All stock except Performer intake and 600 carb.
Don't necessarily need the 3.55 gears but I thought this might be a good price with the carrier and gears. And the 3.55's should wake it up some.

Thanks,
Ken
