EGW has what you need for about $45. if it's an older mkii, the wholes may not match up as savage had a run of bad drilled receivers. if you come across that problem, they also sell blanks where you can get you gunsmith to measure and drill the base. (egw will swap it for a blank) that's the problem i had however the mount is worth it even if you have to go that way.
I have a new Savage Mark II BTVS. Love my new 20moa rails. Bought one for my browning A-bolt and also Dads Browning BLR. Follow directions on the site. My Mark II did have the larger ejection port and I did order the one for the Savage 93 model and it bolted up great. Also my rifles are left Bolts and they work equally well, no problems. Symetrical parts. If you have any other rifles that need it order it at the same time to reduce the added shipping cost. Still only about $20 to ship it to Canada.
Using leupold QRW rings and swapping between scopes have great return to zero between rifles.
