I have no knowlege of those companies, but my nieighbor used: http://www.convertibletopguys.com/home they were very professional and helpful throughout his r & r of a mid 90's Mustang top. They have been around since 1975 and prices are very reasonable (almost too much so) and the product was top notch! They cater to home do it your selfers like us. I will be contacting them for our 69 Deville convertible top. By the way my nieghbor had never attempted anything like this before, they helped him understand how easy it is to do this and he ended up with an awsome looking top. What more can be said? Take care and have fun. Mike
