my rear is shot its clunking and starting to have one wheel peel. I have a 3rd gen rear with new richmond 4.10s and a rebuilt posi. Are the splines the same on both I am wanting to rip the guts out of the 3rd and put it all in my rear, will my axels go right in and work??

 

Sure will
thats what i did man

 

make sure the 3rd gen internals are made for 28-spline, cuz some older 3rd's came with 26-spline. is it the stock LSD or an aftermarket one?
