Hi Bob,
Interesting that Mulfab are not keen on the shorter rebound springs. Did he say why? I cant see what the drawback would be. (altough that doensnt say there cant be any) Maybe a little more body roll? Should not be a problem, especially on a road car. All I can say is it came standard on my roadster and works fine, feels better than the Plus 4 I had before. Personally I would not change the KP's without changing the bushes. I would want them reamed to a perfect match and no chance of sand embedded in the old bushes ginding on the new KP's. Just MHO. All these variables and decisions,

isnt it great to own a Morgan?

I just cant imagine e.g. Audi drivers having this kinds of fun.
