To the OP:

The best place for you to find a Dana 60 in Sweden might be a scrapyard that specializes in US Military vehicles. I'm thinking Germany.

The Dana 60 is a 3/4 ton truck rear end, it was never meant to go under a car. But it was in the parts chain when Mopar engineers decided they needed something stronger than an 8 3/4.

In a 3/4 ton or even a 1-ton vehicle the rear will have full floating 8 lug hubs. The idea is to cut the axle ends off and weld on new ends like 8 3/4 ends so you can use your existing brakes. Then you buy custom axles.

Doctor Diff would be the guy I'd talk to, he would be the most helpful, in my opinion. He could walk you through the steps and help you get the right length axles.

Most all Dana 60s in military vehicles will have 4.10 or numerically higher gears and limited slip differentials.

Good Luck!
