Slant 6 Torque Converter Bushing

IIRC its a 1/8" walled bushing. I contemplated chopping up a few 1/8 drill bits and making a roller bearing like "spacer". I ran a 340 on a 65 trans without the bushing (didnt know back then) and I never figured out why I cracked 2 flex plates! Both times the ears cracked, one time all 4 were cracked through and when I unbolted them the pieces fell out. Bought a 68 trans with a slip yoke, built a driveshaft, bought a Hurst Pro-matic 2 and never looked back.
