Your only option I believe is the BST section. No one that I know of sells eye covers online besides there. Or ebay maybe. I saw a set on there a few months ago.
"The very existence of flamethrowers proves that some time, somewhere, someone said to themselves, You know, I want to set those people over there on fire, but I'm just not close enough to get the job done." - George Carlin (1937-2008)
You're not likely to find them any time soon. I spent over a year finding a set. Very few people part out their NMEs. Your more likely to find a complete marker. Your only other options would be to see if you could get a machine shop to make you a set or modify your marker to accept 2k2 Intimidator eye covers. The later is not the greatest option as the wire channel in the body is still exposed with Intimidator eye covers.
