Hey guys, i just did my 12 bolt swap but my diff was already broken in so this is for a friends. Just put new gears and new eaton posi in a 12 bolt going in a 68 elky. What is the proper break in for new gears and posi? Any recommendations on gear oil for a new rear end, posi additive? I have heard that you should take it easy for a little while and vary your speeds and such on the highway, but just how much is necessary and is this the best way to do it. Thanks.
