61 rearend choices.... making me nuts

i,ve read most every thread about upgrading my diff (stock posi ) and to be honest my head is kind of spinning ,first off my last option is to do any fabricating ,my sbc 385 stroker (brand new) should be making 400 hp and it's mated to a muncie stick,is there any to make it last by doing some upgrades ? or will those 17 splines be twisted up in a heartbeat ,never mind the rest of the diff grenading, i don't have any plans to be drag racing it maybe burn a little rubber on the street,i'd love to be able to just bolt something in it ,iknow it won't be cheap ..thanks skaz

That doesn't look like a bad deal... Are those upper arm mounts the same on the 59-60 as in the 64, or is the EBay ad wrong in that it says only the 64 used those?

Thanks, Mike

Ad's wrong,Mike.I don't think any of them had the 4th. arm from the factory.59-64 HOUSINGS ARE THE SAME.
