So I have a JC Higgins Model 50 I picked up years back in .30-06. I have decided to install a Timney Featherweight 201 using the original stock.

Upon installation, I noticed the stock is not milled like a regular stock with a nice big hole for the trigger group. Rather, it's a small, stepped opening for the original trigger to allow clearance just for the sear. My question is this.

Am I looking at this correctly in that I will need to inlet approx. a 1" x 1/2" wide section for the trigger to fit? For those that have installed this trigger in a JCH 50, is that right?
