I frankly would find a good local garage. For most things appart maybe king pin replacement they should be able to service your car.
Yep, a good local garage, ideally one that has been established a while and looks after old Land Rovers or other classics is easily capable of taking excellent care of a Morgan. All the chassis/suspension bits are easily understood and very familiar to an experienced mechanic, and none of the engines are particularly exotic.
I have a great local place that I use for MOTs, there's always a fair number of Land Rovers and assorted classics outside, and they always like having my Morgan in for its MOT, although they do joke a bit that there's never anything to do to it as I do all my own maintenance.
