Dave,
        I live in Colo. and this weekend we have the English car conclave and 
Rocky Mtn vintage racing {R.M.V.R} will have a booth set up and I will ask 
them how the rules work. I think for racing having a 4 speed may be more 
advantages? I know they say { R.M.V.R} you can only beef the car up to the limits of 
the year of production.What time of day can I reack you?
