If these are what you are talking about,

As with many aftermarket parts, they are no longer made. After switching to the XF6 Offset Triple Tree, I sold my Cobra Triple Tree Covers on our Classfides board, to a member in Texas...
I remember watching a set on eBay go for over $400 (close to the price of custom triple trees

). I bid up to $200, but then just watched and shook my head. A month later, I found my set on the classifides, for $100...
eBay, or the VRCC classifides... Good luck.
