That's a little too busy for me. 2-3 months? If you are sure you have the correct phone number and email address and they do not respond, move on to plan B. Not passing any judgment. You can use them again later on for something else. You should have been searching the internet/craigslist for doors/donor trucks. This hobby takes a lot of scrounging. You can't sit back and order everything. You build a network of forums, people, search places, bone yards and wanted ads. The 64, 65 and 66 years all fit. There's re-skinning or repairing your old doors.
As mentioned, he has not posted since 2014 so could be some sort of sign. No excuse for not responding, if that is actually the case. Not sure what "order" means. Saw specific doors for sale on line and clicked, talked to a real person on phone and ordered ???? Paid money? Credit card payment posted on your account???
Customers are not pests. I'm sure they don't see you as a pest.
I see you have this post so you know the options.
