lavezzitrupos.com is really good, except O.D plug size is always larger than thread major e.g: for .375 -24 UNF - 3B the O.D of plug is Ø.500
Typically, this is true, but you can custom order in most configurations. For example, one I use on a daily basis is a .500-20UNJF-3B and the probing surface is also Ø.500.
