Unbolt driveshaft and axles. Slide axles out a bit

Divenut said

I have a 742 in the Duster and think I'll got that route, i.e. find a chunk, get the 3.91's set up. Then find a local FABO member to help me swap it that first time :)

Remember, you dont need to look for specific chunk if your gonna have 2 any way. Could find 741 conestyle suregrip cheaper pending gear ratio.
