I acquired a 110L firearm (manufacture date before1999, according to Savage) and have been trying to purchase new bottom metal but can't seem to match up the center to center screw distanced. I'm measuring approximately 4.514". I'm finding 4.275" or 4.423" or 5.065". Does anyone know if these hole distances are correct for a rifle of this vintage? It appears to have been a side release detachable magazine originally at one point. This has been modified to hold more then the standard number of rounds. This rifle has been used as a match rifle.

Thank you.

Bob
