Nope, sorry, I don't follow. This sentence confuses me - I don't understand what you're trying to say:
Your dimensional statement equates the shim that I mentioned on the wedge that is tryin to be temporarily repaired, and not to have happen again with a new wedge.
Colt's drawings do not specify a location for the wedge. As Hawg mentions, however, the cylinder end gap is specified, so that's the critical dimension, not the wedge location. It is true that the wedge determines cylinder end gap, but both wedge and arbor slot wear make it impossible to say what the wedge location must be to obtain any given end gap value.
I will agree that, in most cases (not always), setting the end of the wedge flush with the side of the barrel assembly will provide an end gap within acceptable tolerances. But we have a guy trying to figure out what's wrong with
his gun, not what works 'in most cases'. He may have any number of problems, and I believe that in such a case it's important to start by measuring the critical dimensions so that he can begin the process of trouble shooting the problem.
And Hawg, you are correct about the max end gap tolerance. However, I don't like to let it get that wide. .010 is maybe ok, but I'd rather see .006 or even .008. As for the minimum tolerance, I see nothing wrong with .002, other than the possibility of fouling closing that up and causing interference. I think it's acceptable but not optimum. For the purposes of troubleshooting the OP's problem, I think it's ok.
