AMC use to produce these, and I'm sure other folks 'll need them too.

I'm not really sure what they look like, just looking at the Performance American Style guide from 1980 & it's telling me I need this, it just gives me a schematic of how the crank needs to be machined. Please tell me you know what I'm talking about (I Cant find one & this $10.00 piece is whats gonna end up holding up the completion of my stroker project).

Thanks, Tim
