Hi, new to the forum and trying to help a friend of mine who isn't very internet savy. He has a 1965 Mustang with a 200 in it and we figured out someone plunked a carter YF on it explaining why it has a bad vacuum leak at the base. Inline Classics lists an adapter to mount this carb to the 1.5 inch opening head, but I figured out looking through the forum posts the sad situation there. I was wondering if anyone knows a different source for an adapter to fit a 1.75 base carb to a 1.5 head or any tips or tricks to get thgings mounted. Thanks!
