So I think I've located the 7 blade 2863216 18" fan and the AC pulley now to get the rest of the small pieces gathered up to try it out.
that is great looking work tim.So here's some of the conversion brackets I designed and had made. For 22 to 26 radiator. I even put the original slots for the AC condenser in, in case I can use them.

My fan should show up early next week.
If I understand right the 16 has more pitch, 2.5" when laying flat on table I think.
