It's a two piece set up.
You need the side plate and then the scope mount.
Let me know if you need the numbers.
I just did the same set up twice.
My set up had the scope pushed way forward too.
They make a longer ring mount and I am almost convinced
it would work on this rifle.
One on the same rifle as the OP and one on my Winchester 69A.
And on both, I found the scope off center of the barrel.
Meaning the center of the scope is not directly above the center of the barrel.
I found H4831 a set for his Winchester 69A and his sits directly above.
Go figure.
I had Murphy hanging around for a period of time I guess...........
The only thing I found with those rings is they bite the scope tube.
Real easy to do too.
