Good luck man. Those have become as rare as hen's teeth as they say. I had several receivers and parts that I finally tried putting together last year and realized I'd sold all or most of my scope mount covers and didn't have any covers to complete the rifles. I then went on a spree trying to pick them up whenever I found them. I managed to get two of the ones with the mount removed from the cover so all that's left are the four little screws that press on the sides, and I got one see-through cover that I can use. I have a couple of non-see through ones that I may try removing the scope mounts from once I get my drill press back up and running.
Just about the only luck I had was a few weeks ago at a gun show I found one guy selling a plain cover for $15 which I immediately snapped up. I guess my advice is to go to gun shows, and look carefully through the used parts lots. I'd recommend that anyway as it's where I've found the most bargains. It also pays if you know what to look for - last month I got 2 NOS Cobray pouches for $10 each and turned around and sold them on another forum for $180.
