Seth, figure out how much clearance you have between Carb top and frame. You can check this by rolling a drill bit around the frame.. Is it a clearance problem only on one? You needless than 3/16 room.
Measure the distance from interference point to weld at rear of frame tube.
It sounds like it will work, if you can take, the carb top off the carb, while in the frame. Failing that carb, can be lowered, but probably. Not necessary.
