Does Anyone Know Where I Can Get The Hammer Release For The Colt Open Bolt System

[A&S Conversions]

Does anyone know where I can buy or get the specs for the part on the open bolt auto sear that releases the hammer so I can have it machined? I tried to buy the complete set on Gun Broker but at almost $2,500 is just too rich for my budget. I do have a fire control set coming from the Tactical Innovations AM15. I also have a friend who has a Colt open bolt carrier. He said that I could use it to get the specs from. So the only part of that system I am missing is the trip that releases the hammer from the auto sear location. Any information would be greatly appreciated.
