At first I thought you meant Factory Team bulkhead.....That sounds like a good idea those little 2-56ers strip out very easily. I am going to cut off the dimples and use a 4-40 tap and use something about 3/8 long. I heard they cut the rear dimples off the rear u brace "for the gearbox" also. Sometimes it can be a tight fit to snap in the gear box on those. I usually just clean up the gearbox. I may just do the u brace mod.
