50's Morgans are not all that different to the current car's in terms of chassis/frame as you will know, the early engines are pretty gutless. The chap who bought my 59 4/4 is planning a period supercharger, as the 100E's are great units. The Moss gearbox without syncro is an art.
Anything 70's on you'd had best of all worlds, I just picked up a 2015 4/4, it's a dream
