Hi all, I am building a MK4S Douglas.I need a rear oil seal for the engine,it is a pequliar size and I have not been able to track one down.This machine was fitted with ball bearings in the steering stem,I understand that a tapered roller set up was available in a common Timken size,if so, could someone supply the part numbers.I intend to build this bike to be my main ride,having fond memories of owning a MK5 back in 1958.
Regards, Mark4S
