A Mopar guy!! Had a few late sixties Belevederes with slant six/318/383 that I rebuilt. Woul love get my hands on a Challenger or Charger to go through. The boat's "done".........thread hijacked....
That's really expensive for those simple delrin sheaves... I'm sure you could find the same sheave dimensions in a stock Ronstan or other brand sheave. I can't find anything that is a direct match to those dimensions, but FYI, these could work;Rig-Rite does have the gooseneck sheaves. 1 inch diameter, 3/8ths inch center, 1/2 inch width. Made of Delrin (their part #K-11726 s4). $26 each, as of 10/18/16.
I meant to give you the link directly to the product I was hinting at... Click on the 'machine to size nylon' pulleys... They have 1 inch dia x 1/2" wide, you just have to drill out the center pilot hole to 3/8". There is a Schaffer delrin sheave that is very close, but not an exact match. At the end of the day, delrin is way better than nylon (UV exposure), so I guess $28 to have the exact match isn't that bad.Thanks. I checked McMaster but didn't see anything really workable. In boat buck terms, it's only a nickel!
