Great, thanks for that. I would have assumed there were more than 5 different ones, that makes this endeavor a bit easier. Do you know how the ".75 ratio adapter" comes into play? I'm guessing it goes in line with the cable somewhere...
The only ratio adapter I ever saw years ago was near the transmission. I think it fit onto the trans somehow, I guess it went into the trans and then the cable attached somehow? I hope this helps.
