If youve ever tried to adjust your open primary drive with any one of the existing 4 speed transmission plates out there you know they dont work and you end up with a pry bar trying to twist the transmission in line. We have solved that with the FNA twisty transmission plate. Each side you can both push and pull until you get it lined up, no pry bars or screw drivers, just adjust the nuts and righted it down. Nuts are captured by the bungs so nothing can rattle apart. All stainless construction and tumble finish.
