Now this is straight off the top of my head, so do get too upset with me if I have overlooked something - but if you coud turn a couple of pieces of delrin or something simliar to match your choke and then center drill for two laser pointers - I'll bet you could get close to the phyiscal convergence. A good friend with a Lathe might be required.
