I know what yuo mean! I built a racecar last year. Ford Escort -77 mk2 with Coswort engine and everything!

Escort
Escort on the ice
Sideways

But it is little bit easier to find stuff for these cars from Finland, because i am not the onlyone whose crazy. I hope your project goes well! But i have ordered quite a lot of parts from England. They are cheaper there than back home. I use Ebay alot!
