https://smsautofabrics.com   They are the only company that I know MAY be able to make a complete kit. I purchased from them for my 51 and the product is excellent. They are however very hard to deal with . Their delivery times are long and they have no problem giving false information. I don't want to say they will not be truthful but from my experience they are either incompetent estimating delivery times or untruthful. My 4 month delivery time turned out to be two years and there were several controversial  conversations during that time. The only thing they were quick to do was collect their money up front. You can check reviews online .

I will admit I was hoping to hear some company handle them on their catalog, with original materials. Somebody perhaps like Hampton Coach (which I understand are no longer in business). 

SMS has a lot of material, but I understand what you say about the time it takes to get something from them. I ordered some vynil tops about 7-8 months ago... still waiting...

Thanks!
