Marlin MR-7, Long Action, One Piece Scope Base

[MTHokie]

I have sleuthed the interwebs fairly well, I think, including a question/response from Leupold Cust. Service. Trying to find the subject scope mount. A single-piece (weaver/picatinny preferred, but at this point I'm no longer picky) scope base that fits a long action, right hand, Marlin MR-7. Palmetto State's website says that a Weaver 48099 will fit, however, it does not - that one is made for a short action. Leupold says they only make a two-piece. Weaver's web tool says that they only make a two-piece. Anyone got any ideas for me? Thanks!

To follow up, if anyone ever has the opportunity to care about this subject, contrary to the statement from Leupold, their one-piece Backcountry scope rail model #171342, does indeed fit a Marlin MR-7 .30-06 perfectly.
