Norwood, 4birds, Cliffhanger, A Schaub and Weranc55: Thank you very much for the compliments. They are much much appreciated.
klunde, I would think the masonite sandwich is plenty stiff, skip the plywood. Regarding rafters, I would suggest storing in a climate controlled environment, so if the rafters are part of the climate controlled envelope, that would be fine.
Klunde, you may have done pretty good purchasing a kit for a Lucy car you don't own yet, because I am very sorry to report that I have sold my last White Stripe kit.

I have just a precious few blue stripes kits left as well. I've turned off the website 'Buy Now' button for the white kits for now, and instead turned it into a link to my email so I can continue to gauge interest. The blue stripe kit 'Buy Now' button is still on.
I made several promises to the hobbyists on these forums and to the owners of '70~'72 TA's, most of which I've kept, including selling individual parts out of kits etc, but one promise I made is that I would not have a waiting list like the one that existed over a year ago by one company (that I was on) prior to this product coming out.
So, it's time to once again check in to see if there are still folks who need or will be needing kits over the next year or so. I would like to see how much interest there is, to possibly run another production lot of kits. I have some other ideas regarding next steps as well, so I'll keep everyone posted on this topic, but meanwhile, feel free to let me know if there is still a need/interest going into 2014.
What ever the next move is for TransAmStripes.net I want to once again say thank you for EVERYONE's support through this project, and thank you for the purchases. Being a GM Restoration Parts license holder and filling this gap in the hobby to produce this awesome product has been a very rewarding experience!
With all that said, here are some pictures a customer sent me just today of his beautiful Cameo White TA with a recently installed Blue Stripe kit!
