They have a website. Go to it, check out the products and look for the SKS accessories (if the following doesn't work it is
www.rifletech.com)
http://www.rifletech.comI would telephone them and tell them what you have and what you want to do. Many, many years ago, when I did this, I told them I already had rings with my Tasco Pro-Point red dot I was going to moutn. They sold me the scope mount for less than the advertized price, but didn't include the rings they normally would have. Good folks.
Good luck and let us know what you do and how it works out.
Again, scope height was very important to me and that is why I choose this firm. The replacement cover I got required a little bit of hand filing to fit but fitting took no more than about 2 minutes. I is very tight and hasn't move around at all.
