BC, Frank is right, don't mess with this stuff, you'll break a wheel at some point.
If you do not already own the Trigo wheels and adapters, there are alternatives,(my opinion, I am not an engineer) PS Makes the Halibrand wheel you are looking for. If I were in your shoes, I'd buy a full set of new one piece hubs made to suit GTD uprights and the Pin drive wheels PS Engineering makes. It is a no-brainer Simple, clean, fewest parts, fewest mechanical interfaces, fewest things to worry about. Brian
