hubcapsc,
I also have one of the Cobra reservoir covers. I have always thought it looked a "busy" but after I installed it I have been too lazy to change back. Cobra made some replacement grab rails (fender rails) using the same concept. In three years, I have only seen the grab rails for sale once on ebay by Michael J. Terry. I do not have a photo of the grab rails.

Mike Terry has the rails on eBay now with a buy it now price... Once they were on there straight up (with a reserve), and I got the high bid on them but didn't match the
reserve... if I had the cash right now, I'd probably get the ones he has on eBay now.
Cobra also made radiator side covers - I found some new, covered with dust, in a shop last year:

So far, in the same pattern, I have the Cobra radiator side cover, handlebar reservoir covers, carb tops and now the rear brake reservoir cover...
If a set of the billet light bars ever comes around when I have the price they demand, I'm probably doomed

... and the rails...
Want to sell your busy old brake reservoir cover

The chrome on my plastic one started to bubble last year, so
I got a fairly new one I could send you ...
