Hi Dan,
As you know I love your car and am over the moon to know your moving in this direction. The sight and sound of a fully prepped Classic Adelaide Mk 1 Cortina is a beautiful thing. Good decision!
Now if your going to head in that direction.....as you will soon find out the Classic management are sticklers for vehicles being techincally and period 'correct'. Sooooooo maybe some of the hero Mk 1 Cortina's from the past could be your way forward in the future!
I refer to the cars that created the Mk 1 Lotus cult.....cars you could draw on for inspiration and possibly replica one! I have for a long time wanted to replica an EX-Works Mk 1 Cortina Lotus....and utilise our great no. plates to truly seal the deal!
Here's a couple for consideration;
Colin Chapman's factory machine;

Sir John Whitmore's beast - Alan Mann style mMMMMMMMMM[^]

Mate I am stoked your evolving your Mk 1....please keep me in the loop......I smell a ride along feature article for Classic Ford!!!!
