Need some help confirming what measurments to order.

Howdy Gang,
I'm going to start looking for an aftermarket stock for my Hog Hunter soon. I thought I had scored today when my local gun guy had a Choate Varmint stock for a Savage SA with top bolt release that he offered me for $50. Unfortunately, the hole spacing is wrong and it appears to be for a staggered mag setup. Mine is a center feed.
Does anyone know exactly what I should be ordering if I find something I like on line? I'm assuming that this rifle is a Model 10 style, short action with 4.4" hole spacing and center feed blind mag. Is that correct?
Thanks,
Doc

If it's 4.4" its a short action centerfeed

I need to find your gun guy.lol

Buy it anyway and use it to barter. Let someone have a good deal and make a good deal.
