Pinto Car Club of America

I have always been fascinated with anything Ford.  I came across a Pinto Station wagon with production date of 10/75 (presumably a 76').  The 5th digit in the VIN was a Y.  The vehicle has some goodies; including, air conditioning, powering steering. 

The Compressor bracket had an engineering number of D4ZH-2882-AB.  The alternator/smog pump?? had eng number D5ZE-10039-AA.  The power steering pump brackets (2) did not have any part number associated with same. 

Can anyone tell me if these parts were used on just Pintos or other Ford/Mercury makes/models, engine sizes and years? 

I have added a photo of the engine bay as I was thinking that the engine may have not been original to the vehicle. 

They were also used on bobcats and mustang II with the 2.8 , after 79 the 2.8 was not an option anymore and the A/C compressors changed later , here is a photo of mine with all the stuff hooked up ,

Thanks for the reply.  It appears that the engine that I photographed would have been swapped out at some point given that the VIN was a "y' code which would have been the 2.3 4 cylinder? Am I correct. Or, was a/c braket, alternator/smog pump bracket the same for both the 6 cyl and 4 cylinder vehicles?
