1903 Springfield Sporter

Okay, I know this is frowned upon, but I recently picked up a nice 03 that has been sporterized.

I have a nice original 1903 and a 1903A3 in original condition. This was such a good deal I could not pass on the rifle. The question I have is about the spacing of the screw holes already drilled into the receiver. I found a nice Redfield JR. mount to go on the rifle. The front spacing is correct but the rear screw is about a 1/32 off. The rear screw spacing needs to be about 1/32 inch shorter. I can't seem to find anything on the screw spacing of mounts that were made to fit the 03. Since the holes have already been drilled into the receiver I would like to mount a scope on it, but I do not want to drill any more holes. Anyone have any ideas? I am not interested in the S&K mount. Do Leupolds have the same screw spacing? I suppose I could use a dremel to oblong the rear screw hole in the mount if necessary.

Thanks

sounds like a Bueler mount was on it at some point
