FOUND Non a/c and non p/s single groove crank pulley

[Nirvana]

Just need a single groove crank pulley now for my Duster 400 build. I believe the diameter is around 6.5” or maybe a little bigger.

I only have pre 72 staggered bolt pattern.
But they are non pitted, blasted and painted- $30

I would have to elongate one bolt hole right?

1 hole gets elongated.
Manual was less common after 72.
So fewer even spaced single groove pulleys to find. I looked through mine, no even spaced.
Or pull the cast crank, swap in a forged, get it internally ballanced, run a early staggered bolt pattern, zero balance balancer.
