hi, im messing with reinstalling the factory ac on my 67 dart gt, we swapped in a 74 slant when the stock slant threw a rod, im trying to figure out how this thing goes on there, when i set it up like its supposed to be, (two braces, one on top the head, one on a engine bracket, and two bolts on top of water pump) when i had it most of the way tightened then the bottom pulley on the ac was rubbing on some parts from the power steering, ive already determined that i need the double pulley for the fan off of the 67(just swapped out the water pump and had the whole thing disasembled, now i have to take a bunch of it all off again ) other then that im lost, its just not right for it to rub like that and i dont think the belts i have left over from the 67 are the right length the way i was looking at have it set up, so can anyone tell me where the belts all go and where on the main pulley(off the crankshaft) they all go? ive got three spots for belts...also, the 74 had aftermarket air, i dont know how that hooked up, thanks!

There are two different PS pump pulleys, one is somewhat flat (non-AC) the other has a big "bell" shape. (AC version) There are also different brackets that position the pump correctly to the pulley groove.
On my SL6 cars, the PS pump runs off the first of 3 crank pulleys.

that makes it a lot clearer, its got a weird looking nut fastening it to the pump, it doesnt really have much in the way of flat spots to get a wrench or anything on, am i wrong on that? do i have to switch the entire pump or just the pulley? thanks!
