Question about Roadmaster headset size

[RatRod Diva]

Hey guys!
I need a little help with choosing the right headset for my roadmaster. The readings I seem to be getting say I need a 22.2 x 32.5 x 27mm headset. Is this exactly what I need or will any 22.2mm fit? This would be for vintage Roadmasters...mostly prewar i.e the luxury liner and a few other models.
Thanks!

Seems like the older stuff is more likely 21.1/ 32.5 / 26.4, you can get away with the 22.2 with older 21.1 quill stems but it helps to get one of the Wald shims to take up the slack.
