Does anyoen know anything about modifying the BTR78 axle to suit a TA22? I know you need to shorten it etc but what have people paid to do that? Also what other options are there for calipers on these things? the old style ones look dodgey. What is the likely price i could pay for an LSD centre? At the moment it has a 3.89:1 open centre in it. Can anyone tell me a little bit about these diffs.
