Guess picking the right parts to make it work can be very trying , wish I had photos to share but long since gone after 45 years ,a couple of divorces and a house fire you lose memories and most of your mind , know I made it work , with the excellent job that your doing to make it perfect any info will help from the past ,, what I do remember that the best damper (at least for 71 to 73 ) was the thin one , three bolt with a flat pulley , the one I use was off a dealer installed A/C that was cast iron and three groves , machined off two of them , the water pump after the mods done to it made the edge almost touched the water inlet on the pump after the bearing and flange was pushed to almost touch the seal inside the pump ,(or see it at the weep hole one the side , somehow the belt lined up and the back of the alternator just missed the back of the block , the radiator support brackets I put on backwards so I could make spacers to move it forward to the max to save space , the fan was a flex one with it bolted straght to the pump , guess some one will see this post and have a pile of 302 pumps and covers to see what is shorter , their is some company that did make a real short pump and pulley set up , dont know if they are still around but will check and post if they are to save time and gray hair pulling , later and stay safe , Blaine
