Where can I find written directions for installation for open cat top
Mac's has them for the Cartouche tops they sell.
Go to the Classtique Upholstery website. There is a clickable link on the upper left of the home page that will send you to how-to videos posted on YouTube.
John, If you are using a kit the bows must be the correct length. If they are not spot on you will have to have the top custom made.
I installed a Classtique kit on my 1924 touring / pickup conversion, and helped another member install a Cartouche kit on his 1926 roadster. My personal observation from these two data points was that the Classtique kit had more "allowance" (extra material) to allow for slight adjustments / variations in the positioning of the rear curtain and top.
Here are links to the Classtique videos:
Thank's for all the information - very helpful
