Decided to ditch the chain drive, and welded shaft and go with a LJ80 trandfer case instead. Also clocked the engine and going to install it sideways, using the rear axle output to power the transfer case. In order to do this i put the rear axle output back on that i removed yesterday :
But i don`t need the vacuum 4WD actuator, because it will always be engaged, so i cut of the unnecessary stuff:
That`s the transfer case:
This gives me a nice and clean drivetrain, lots of room in the rear car and a lot better speed range. Really happy about that...
