Therefore, to use a non-overdrive or A-Type opverdrive, you have to use a special adapter bracket that wasn't used on earlier frames. The mounts on the later models with the J-Type overdrive were 2 round rubber mounts verses the single rectangular rubber mount used on earlier and non-overdrive models. I think I still have one of these brackets left over from my racing days. I used a later TR-6 frame under my TR-4A.<br></div><div><br></div><div>Jack<br></div>
