B-Square Scope Mount Drill Jig

I have a B-Square scope mount drill jig and only have a drill bushing for a #31 drill - I need a drill bushing for #28 - for those of you who also have one, since B-Square no longer makes this rig, do the drill bushings from Forster or Williams Gun Sight fit this?
 
The Forster bushings are 5/16" OD x .750" long, under the head. You can buy drill bushings from MSC and other industrial supply places. Also, it's easy to make your own out of drill rod. I have made many drill bushings out of O1 drill rod and hardened in oil. They work great.

Even unhardened they will function fine for a few uses.

Best of luck! Joe
