Am curoios to know if a LN Frog for a #7 will fit the Stanley Bedrock it was designed after. I've got a very flat 607 and rather than looking for the new lateral adjuster and figuring out how to get it on as well as a worn depth adjuster, I was hoping that a new LN frog may solve both issues. They are not unreasonably priced, but it seems too good to be true. Anyone know?
