Welcome to the club!
I have a Duchess also.
I understand Classic Roadstes II still has some parts for our cars. I have not been in touch with them recently. But at least one other forum member has. You can try to call Don at 888-722-6272.
You can get your fender mirrors from Moss Motors. I suggest the convex lenses for both sides. Moss Motors has them for only $14.50 each. Plus $2.00 for two pads.
Clssis Roadsters may be able to make a top. They made one for me, form old patterns, but that was over ten years ago. If not, most folks I know have gone to a boat top place. They’re used to sewing canvas and vinyl roofs and curtains, with no liners, like our cars tpically have.
MG Magic (a place in Florida, phone sales only) is another good source for parts for various TD replicas.

Good luck. And keep asking questions!
