Ah gotcha, you're talking external engine parts, i meant just the engine itself, block, head, pump.
Transfer all your accessories and pulleys etc over from the Montero, motor mounts are similar, if not the same between the truck and van, either way their mounting points are identical on the block, so you're headed down the right path on buying montero mounts, ive found the mounts to be the same in appearance for most the RWD 4 cyl engines, diesel, astron, sirius, from 1.6 up to 2.6, if bolted in the RWD configuration, it seems to just use the two bolt lower with stud upper, flat mount.
