I have a 63 chrysler with the 741 carrier(open)i want to put a posi in that rear end housing but from what i,m told i need to add axle shims when your going from a open rear end to a posi...mancini does not sell those shims..any old fart heads know what thickness shims i need....my chrysler books say i need them but they don,t say how thick or a part #(these axles have the big nut that hold them in)
thanks in advance

I cant answer your question but that big nut at the
drum is what holds the drum on(with a key way and key)

Hi,
I've done this before, the axles were shorter on a sureqrip back then, but I did it by taking a the flanges of a later bolt in type axle and cutting the center out of them so all you have left is the ring with the bolt holes in it. they're about 1/8 to 3/16in thick, that's about how much shorter the axles were, then you use one on each side and then play around with the stock thin shims that come with a open rear to get the end play you need, around .008 total. I've got some stock thin shims if you need some more to play with. either that way or you have to cut the axles off. it will also move your brake drums out a like amount which shouldn't hurt as long as you don't have a rust ridge where the shoes don't run.
