Someone might be able to help if you post a picture of the bottom of your action. Also measure the action hole spacing. Should be right at 5.0". You may be able to attach an old style staggerfeed blind magazine box (with lips) to the action. then you can use any Savage LA aftermarket blind magazine stock.

Do a web search for "S-T Rifle Stocks Accessories/Numrich Gun Parts". You might be able to find a discontined Savage LA stocks with the side magazine release.

If you want a DBM and more aftermarket LA stock choices (ex. Boyds Tacticool), then you will need the newer Savage LA centerfeed action.
