I wonder if there is a special secret department at Morgan to research good authentic vintage squeaks, it is uncanny driving a brand new car without any at all but after about 700 miles on they come. Said Morgan secret department probably called MOGi8 or something very good they are too. I spent quite a few years as a bus engineer where I spent time curing various faults but there is usually room to work on a bus, do not fancy cutting out floorboards to stick my head through to watch the suspension as I did on a number of occasions, so back to trial, error and guesswork but keep the suggestions coming something will match the tinkle my car has when not on load.
