The time for action is past.
Now it is time for the paperwork..
Over the weekend I had the engineer and the Historic secretary from the Jag club look at the car. Both have reported favourably.
I have submitted the "Application to Modify a Motor Vehicle" form to the DOT. At some point hopefully they'll reply.
When I have that form back, I can book the car in for a registration check, where they inspect the car to make sure that all the numbers match the paperwork.
If I pass that, then I can book the car in for a roadworthy inspection by the DOT, which is usually like the Spanish Inquisition without the comfy chair.
If I pass that, I can then go to motor registration and actually register the car.
And....DRIVE IT!
