ATI damper w/Chevy pulley pattern questions

My buddy had a ATI damper on his Small block in his Plymouth Arrow with the Chevy bolt pattern. His engine was mounted with a front plate and mid plate. He used a pulley for the small water pump which is close to the damper and mounted the alternator off the engine plate. Seems like the choices are the small water pump and the large water pump, different space from the damper.

Thanks for the response. Somewhere in the dark recesses of my mind, I remember a discussion about using a big block Chevy crank pulley on a big block Mopar with a front motor plate. The Chevy crank pulley would push the crank pully groove out to keep it inline with the water pump pulley groove that had been bumped out by the front motor plate. The article (?) gives the part number or size of the Chevy Pulley needed. I wanted to find it (article or part number) so when I sell the motor plate and damper, I could include it for the buyer.
