I'm rebuilding a 240 motor and need some help. I took my machinist my crank pulley and he said it looked scary. the embedded rubber was in pretty bad shape and he was concerned about its stability. I want him to balance everything but he thought I should try and find another pulley. I'm up for ideas. This is my first thread so I hope I'm doing this right.

I believe that Motorsport Auto in Orange, CA now has them for sale. $$$$ (at least I was told they did)

Occasionally used ones appear on eBay.
