'64 \6 Choke Bimetallic Spring

Looking for the divorced choke bimetallic spring assembly for a '64 Dart with 225 (or just the spring).

My spring appears to have a tiny bit of the end broken off, and can push the choke butterfly closed, but not pull it open.

NOS units are disgustingly expensive, and I don't need a new one anyway – just one that works.

I'm sure one of you guys who converted to electric choke has one lying around!

Thanks,
