Help with scope base

[Bowdacious]

Could someone please point me in the right direction on which scope base I need for this gun. I am not sure if the holes are aftermarket but it appears they are.

Not sure of the spacing but it looks to be a sporterized '03 Springfield correct?

Looks real similar
The gun says US Remington model 03-A
