I do not know how they were manufactured, but they are now rare as hens' teeth. I might be tempted to buy if I knew that I could score the matching Cobra rear fender rails.
I bought the Cobra rear brake reservoir cover for $20 back in 2008. Last one I saw on ebay went for over $120.
I got my Cobra rear brake cover on eBay for $30, included a OEM rear brake master cylinder cover...
Got the radiator side covers for $130 from a cut-out bin in a rural Honda shop.... it was like
a sickness after that, I paid Big Mike dearly for a set of the Cobra rear fender rails and
a Cobra light bar

...
PayPal has since cut me off... there's a "sending limit" beyond which they require that you
"link your bank account" to them, or get one of their credit cards. It will be a cold day in
heck before that happens, so I just have to watch stuff go by now. Sometimes eBay sellers
will let me buy stuff with a Postal Money Order, usually they just say "no"... I had to watch a
set of Cobra cam-end covers disappear for cheap not long ago... there's an apparently
mis-labeled new Cobra lightbar on there right now that's only up to about $150 with just
seven hours to go, but the guy won't let me bid on it without paypal...
