I took the stock 216 out of my 1951 3600 and replaced it with a rebuilt 1958 261. It has Fenton dual exhaust but I retained the single intake and single Rochester carb. I'm not having any luck getting the throttle linkage from the 216 to match up given these changes and wondered if anyone has figured out or knows who makes a solution for this? Patrick's say they have a solution but it could be quite a while before they are available.
