Guys, buy a stock seat pin with rubber washer. Install the pin in the lock, now put o piece of glazing compound( or other sticky clay) on top of the installed pin. Put the seat in place, sit on the seat. Your new pin is now stuck to the seat pan. Put key in the seat lock and turn, carefully remove seat, if you are lucky all the clay has squeezed out. Mark where the mounting holes are,drill and install pin to seat pan using Pop rivets and u are done. You may find that all the clay has flattens, in which case you will need a shim of that thickness, between the pin and pan. The seat pan actually has a perch where the pin will go, like it was made to use the stock pin, but Corbin in all their wisdom decided to use the most butt ugly method, imho. My bracket was black . I can't even imagine how a yellow bracket would look.
