Great, glad it worked and glad you found the stops.
As far as being anal, you will have to get up a little earlier than that to beat me. I nickled all the usgi internals in my post sample just because they clean up so much easier and slide so smooth. I also took an unfired usgi bolt and a few cutters and a step drill, turned it into a colt spec bolt. Then I nickeled it of course.
Just remember, if you use a regular 1919 bolt you will have to use the gi backplate, driving spring and guide unless you modify your bolt to colt spec because the driving rod passes through the front of the bolt on the colt setup. It also has a relief in the back so the bolt wont beat the rear of the guide rod.
