I'm running 2wd Montero sport front calipers on my 89 v6, with the M.S. dust shields. You still have to trim about 1/2 in off the shield to make room for the bottom of the caliper cause the bolt hole are slightly off.

2wds are alot easier and faster to steal parts from, they are newer and not as corroded as the 4wds. The calipers are the same as gen 2 3.0s.
