Hi George,
There are not many fully built GT40 replicas in Canada, however as you are open to a project or a done car, I may be able to help you.
It would be good to know what you're looking for in terms of type (Mk1, Mk11, Mk1 Gulf Spec) Small Block or Big Block, right or left hand drive, Track day car or street licensed etc.
Of course if you're building the whole car then you cam make those choices on the fly.
It's a ton less work to buy a properly built and sorted GT40, so tell us what turns your GT40 crank and see what comes your way.
Also, welcome to the GT40s Forum!
Cheers
Ian
