Hey DaveinGA post up some pics if you don't mind. I have a super like you and mine is a bit high as well. I just want to see if yours is similar to mine or much higher. I have been able to zero in with mine which BTW, took quite a bit of time.
Here's a couple pics of mine:
Rail related to wood. Notice how high it is on the receiver. Almost up to the bottom of the dust cover.
Rail picture with stock removed.
Top view to show how rail is mounted and how far left.
Link to a picture of the style of mounting I think the rifle should have come with:
Have a look at the Kalinka weaver top mount - it is much better than the side mount. I found the side mount was too flexible.
The super has a dovetail on the rear sight that this mount clamps on to. The rear "legs" need to be removed from the mount.
I agree this is the mount that should have come with the rifle, but I think a better solution than removing the rear support legs from the mount is perhaps to remove the side rail, then install mounts for the rear legs of this scope mount.
