just found a decent facility that manufactures convertible tops of many many makes and models. and specifically older cars. thought it might help someone out. the company is Robbins Auto Tops LLC. they are a manufacturer that builds tops.. not just a vendor selling someone else's product. http://www.robbinsautotopco.com/index.php
Thanks, I'm saving that for the top material as I am thinking about doing the top of my 31 Model A Victoria with convertible top material rather than with the Leatherback look.
I used Robbins tops for years when I was doing British cars. Great product and, yes, they are wholesale but have a ton of distributors.
