Kick down 904 bell crank for 1966 273
It's not just the offset, it's also the curve. If you noticed the ones I showed, there is also a difference in length of the lower arm that snaps onto to the transmission link. Inside the transmission, the 4bbl has a different ratio apply lever. I'm not saying you can't get it to work eventually, but, it might take quite a bit trial and error to get it just right.
