3844100AK Pulley photos and dimensions needed of an assembly line pulley

[jbtech]

Luckily I've sourced a stamped pulley (Top pulley). If I can get the current owner of the engine to measure the pulley and check the keyway I can confirm 100% it is a 3844100 (spoiler alert I won't). Bruce (the original owner) did race the car and its not impossible the alt/pulley were changed. I'll be running my stamped pulley on my car for now. It feels like the more I learn the less I know.
