I replaced the studs on my stainless Cooper with regular nichol plated from Uncle Mikes. The stock is B&C, and yes, both front and rear are machine threads. I had to buy two packages of UM's swivels with studs to get two machine screw studs, but they worked fine.
Ended up going this route, GrovTec wanted $25 to ship me 2 studs, I figured for a couple bucks more I can get 2 sets of swivels as well.
