I have done the conversion to a 2004R transmission, but haven't completed the restoration on the car yet and am using a Bowler tru-shift correction system but doesn't appear to be one for a stock two barrel. I have a holly carb so it works for my carb. You might be able to contact them and see if they have one for your carb, but otherwise I think if BTO can do it, that is gong to be about as good as you can get because there aren't many if any company's out there that are making these for the stock Rochester carbs.....good luck and post your updates here.
