I've got an opportunity to buy a Savage 111 for a decent price. The only problem is that it has the side-button drop magazine and a plastic stock. If I get it, I'd want to replace the stock (probably with a Boyd's laminate). I'm assuming that means I need to convert to blind mag. The problem is that I can't find any long action blind-mag magazine boxes in stock anywhere.

Questions:
Anybody got a lead on who has the magazine box in stock?
What else will I need to do a side-release mag to blind mag conversion?
