AC compressor brackets

I used a 1990 dodge pickup ac bracket and compressor, had to change to 1990 alternator also, the alternator from the 71 was too large and would not line up to put the double v belt, make sure to get the bracket that has 2 holes at the back of the alternator, it has 3 holes at front to bolt to front of water pump, i have a high rise intake and was worried that bracket would not be high enough to get back 2 bolts in rear of compressor, but it fit great, worst problem is working around oil dipstick, the front bracket and rear bracket has a brace just above the fuel pump and the oil dipstick fits between the rear and front bracket and you have to decide which side of the brace you want the dipstick to come up on.
