Some background. Saved a complete dealer's A/C installation instruction for 1900/Manta for '72-'75. This has templates for cutouts and everything. Also has detailed list of parts needed complete with pics of those parts. Don't know why I didn't go there first!
Here's my quandry . . . the dual crank pulley shown has the WP/alternator driven off the rear pulley and the WP spacer is used between the pulley and the fan blade to clear the front crank pulley (stock belt path is unchanged)! Looks like my original assumptions (added pulley at front of crank pulley, same belt path for WP/alt) were correct after all!
Figured out where the dual pulley Dave sent was used . . . to drive the 1969 1.9 AIR pump. Thought it was odd that the stock belt path was moved forward and that the pulleys were different size. Anyway, looks like I'm STILL looking for an A/C dual crank pulley . . . P/N 3032075 according to parts book and dealer A/C installation instructions. HELP!!
Bob, Gene, could you verify your dual crank pulleys have both drive pulleys the same size?
