I have not used all the parts from this kit, it was bought as a try it and see as I basically wanted the four nylon drum front bearing pads to try on my old Proline TDC6A as getting genuine ones are at £15.72 each so would cost £62.88 for the correct ones.
Anyway they fitted and after cleaning the drum surface from old dirt seem to work OK.

Not sure about the rear drum bearing as not tried.
