I've been building a Pre-A coupe with Greg at Vintage Motors in Hawaiian Gardens. It's going along well. I, too, opted for this for the build for it's all-weather possibilities (it get both hot and rains a lot in the northwest).
When we started he warned me that this would be a 12-14 month process. We are now over 2 1/2 years. Admittedly, I have a lot going on in this build (Subaru, special interior, a never before done A/C install to preserve the Pre-A dash, AirKewld brakes, etc.), and covid happened (is happening). I hope it may be done this fall. Greg has been happy to communicate with me, and press the build along, but it has taken considerably longer than was represented. I've written two pretty big checks. So if you are not bashful about embarking on a three year process, you'll get a great product. If you'd like to have it next year...forget it. No one can do that for you.
