Trevor,
The toggle switches are much bigger than Lucas parts. Also don't forget the GT has stalk controls as well, so it needs less toggles.
If you are ever up Essex way youcould probably call Roush and ask them if they would let you have a look at theirs.

I was curious as to why replicas of the late shape GT40 body had not started to hit the market yet or is nobody brave enough ????
