When I had bought my bike new, I got those chrome "ribbed" plates that covered the "open" area's on both sides. But when I switched to a Pingel petcock, I of course, had to lose the left one.

So I remounted my coil pack with the appropriate sized threaded rod......."lock-tighted (red)" into chrome acorn nuts, which turned them into "bolts"........which in turn I bolted through chrome oversize fender washers. (x3)
So I at least DO have, a LITTLE chrome in that area!!!!
Not as much chrome as I was used to, but it IS a nice accent, on the "cheap".........
