The Weaver 2 piece bases have had quality issues the last few years, with a lot of folks not able to get their scope leveled and zeroed with new mounts. But, other people have had no problem. So a Weaver #14 and #19 is one possibility if you want to risk it.
Leupold makes a one piece mount which works fine. Or you can get on eBay and pick up some older Redfield or similar bases which use the standard mounting holes.
