Would like to hear impressions of different venders. 914 Rubber seems reasonable. have a 75 with beige seats is it likely seat kits will match match to existing door and back panelsClick to view attachment Click to view attachment

I can speak to the 914 rubber kit.
The original vinyl is not available any longer. There are very minor variations in the texture that are very hard to see even next to the original. The color is matched from original parts for the bottom of the seats that were not exposed to UV.

On to the question of if it will match what is in your car.

Most likely not.

Here's why.

UV will fade and alter color, there are variations in dye lots and what the factory used. This is most prevalent in the tan/Carmel as well as browns.

We can do custom work from a sample, it's just not on the shelf.

Hope that helps.
