[C1] C1 door post differences?
The main difference between all of the posts is in the top of the posts. The 56-58 has one top design and uses auxiliary post weatherstrip with a separate rubber stop. The tops of the 59-62 posts are slightly different and take an auxiliary weatherstrip that has the top stop molded into the weatherstrip. The only difference between the 59-60 and 61-62 posts is the 59-60 ones have the serrated back while the 61-62's are smooth on the backside. With the posts all being interchangeable, the only thing you need to do is make sure you use 56-58 auxiliary weatherstrips and separate top stops with 56-58 posts, and 60-62 auxiliary weatherstrips with 60-62 posts.
