the bits that look wrong must be looking wrong because they are designed specificly for that car with the ac

if you get normal cosie pulleys and belts they hsould line up with everyting else

after all, if you can get the p/s pump and bracket from a normal 2wd cossie (i'm not sure if the 4wd ones are different) they you can swap it all over

take loads of pics and put then up so that we can all see what the problems are that you may be facing when doing the swap, lots of info wouldn't go amiss either
