lakota's got a point,
In 1990(?) TC changed the front tang screw to a "through stock bolt" that fit's into a threaded hole in the trigger guard. Previous models had two wood screws for the tang.
The change addressed an issue they had with stocks cracking. It wouldn't be a big deal to drill and thread a hole but it is something too consider checking.
A great idea is to get Track of the Wolfs catalog for $10. all of the photo's in the catalog are "actual size",, you can hold your existing piece uptoo a photo and see how it'll fit, or if something can be modified to fit your needs.
