72 duster Chrysler 3 speed

An A230 will have the small yoke like a 904. I know that the larger slip yoke that I got for my A833 did not fit my A230.

Brewers Performance sells them, I've seen some on eBay. You could always PM whitepunkonnitro here on FABO, Tony sold me a large slip yoke so it wouldn't surprise me if he's got some small slip yokes he'd sell too.
