I have a 48 Plymouth with suicide 4 door and it already has one of the Roto-Lokits on the driver door and it is worn out. I have been looking for another kit. what I have found out is there are lots of different kits. on my rotor it has circles on one side and one of the circles has a triangle and on the other side of the rotor I have an R this one is hard to find. I have bought a kit I thought would work but the clocking of the stars was off I think I bought a L-1 kit and it did not work. if anyone has different rotor I am looking for one with the Triangle on one side and R on the other. like I had said I already have a repair kit on this car. it is just worn out .
