Frank's conditioning was better years later, but I liked his look here. He was just under 240-lb, and his waist was 29".
On MuscleMayhem, TA's waist his 29" after a weight cut, and he said it was hard buying pants with a waist that small. Under by Mayhem gimmick Listerine, I asked TA "Have you considered a belt?"

Then McGrath posted "My waist was 29" when I was 230-lb."
So I'm assuming that was between his CBBF Canadian Nationals win or the 2004 Toronto Pro below. I talked to Ron Partlow about this...I think Frank may have competed in the super-heavyweight division in 2003 to win his pro card as a very ripped light-heavyweight. Ron may have placed 2nd to Frank there. MuscleMemory would know.

I can't seem to attach this photo from this phone. Here it is:
