Got a buddy with a 92mm throttle body and the tps is too small for the hole. It's a 4 bolt tb on a 3bolt intake. just needing to know what needs to be done for a tps nothing else. Not trying to get into what tb is better or why I shouldn't go with that tb. Thanks.

When I upgraded to a 4-bolt intake and an eBay 92mm throttle body, I used the same TPS as I had with the previous 3-bolt truck intake. When I later upgraded to a better 92mm TB(NW, actually) it fit as well. So perhaps head to the parts store and ask them to pull a TPS from a 2000 Silverado or Tahoe 5.3 for you. See if that is the right size. Or perhaps one of the other folks will come along that specifically knows size difference between, say, F-body and truck or similar.
