Thought that might be the case, good photos and drawing btw. Agreed that to match exactly would mean either someones rare spare parts bin or salvage yard. The alternative would be to find something that looks the part and functions as the stock piece with little to no modifications. I'm sure others will chime in too, here is a link to PIC which has both stock sized and custom made precision shoulder screws:
