10/22 base question

[tntrex]

Does anyone know if weaver or anyone else that makes a 5/8 base for dovetail that will fit the ruger 10/22? I want to put a red dot on it and of course my 10/22 has the 3/8 base on it now.

I'm hoping you guys can help me out.

Ahhh. Figured it out after examining a newer ruger model. The much older ones like I got; 60's model came with the narrower base.

I did find a number To9 on the new one and see its a weaver style. Now I just hope the holes match up when I do get a To9 or other.
