There is a fella named Mike who can be found on the 24Hour campfire savage collectors forum. Goes by Lightfoot. He makes and sells a no drill mount that mounts like a Stith(tang holes and rear sight dovetail)but it uses standard Leopold rings allowing the mounting of better optics than a Stith will allow.
