This is what I'm planning on using for my sedan. It is a universal product made by Metro Molded Parts in Minneapolis Minnesota. The product is called "push on trim seals" and I think the TS 2-C is the version to use. The website does not have dimensions on the drawings so you will need to order the catalog which includes the dimensions on the drawings. Look at the TS 2-C/25 to see the drawing as the drawing is missing from the TS 2-C. The /25 signifies 25 feet of seal.

Click on "Universal Parts/Press-On Trim Seals" then look at the parts.

Metro also has various other seal profiles that can replace most of the rubber in the 1200's. Have fun looking at all their products...
