I have an exhaust cut out pedal that is NOT a locking type but more of a toggle pedal. It was on a T that I had and worked very well. It requires a cut out that opens when you push pedal to one side and closes when you push pedal to the other side, (like a toggle switch). The reason this is required is that the area in the floor for the pedal on my T hack is narrow and the common type of pedal is too wide for the for the hole in the floor. The old cut out assembly I had is long gone. It was a lot lighter than the new ones I see that are available. If anyone has what they think would work or knows where I can find one, send pictures. Thanks.
