I am living up here now in Worchester Mass. does anyone have a local contact for converting my 4:10 rear axle to limited slip?

 

I dont know of any but i will give you a list of 410 door jamb codes that are all limited slip. You can visit your local bone yard and start looking.I am sure some of these are also dually numbers.
B5,,C2,,C5,,D2,,D5,,E2,,F2,,F5,,GW,,H5,,KW
E6(92-98)
EW(92-99)
Happy hunting.

 

Thanks PNOSE, sorry I havent responded before, I am printing out the list now!
