Hi Alex,
That is quite an accomplishment to have collaborated in creating something that special. It is a work of art. When my 5-S is finished, if I can't get it smogged and registered here in Ca., we might have to discuss swapping your '73 Grp4 for my '88 5-S. 1973 vehicles are smog exempt here in Ca. You'd be the only guy on planet earth with two '88 GT5-S cars.
Anyway, congrats on your car. It is magnificent.
David
