I have the Bruce Adams covers for my 190 SL. They don't hold a candle to these. As you said, fiberglass...as in they don't fold and how are you supposed to store them? Yes, if you drop a steering box from a distance above the fender, the fiberglass will give you more protection than these more pliable covers, but that's about the only advantage, which is why I'm having BF make a set for my 190 SL with blue piping.
Fender covers are not on the website, being a relatively new item. You need to call the shop and talk to Michael, 414-228-4899
Yes, that's a dwell/tach meter and yes, I used it on my Mustang in the 60s. It's outlasted several other more modern examples. The timing light is a Snap On from I'm not sure when, it was my dad's. Wasn't really doing anything, just looking to see if everything was still to spec, and it was, and took a look at a plug.
Cool how the piping on the cover follows the line of the door crease.
