I put a bit of heat shrink on the vertical axis post so it does not bang directly into the housing when it is moved fully up or down. this should prevent long-term wear on the housing. I've seen some originals that the metal was literally tearing from the constant banging of the post into the housing.

I've seen some originals that the metal was literally tearing from the constant banging of the post into the housing. How long does the heatshrink seem to last? We used double-thickness metal (and I believe each plate is itself thicker than the original), so I can't imagine the metal on ours will wear out...but it'll certainly provide a softer feeling when topping or bottoming out, which is a worthy modification. Thanks for sharing it! (If I'm wrong and you're seeing significant metal wear, please let us know!) How long does the heatshrink seem to last?
