Fixing my TK26'S

the replacement carbs i put on my GPZ550 kept fouling plugs due to the restrictive muffler that's on it so striped them down for rebuilding and have found they have 115 mikuni jets installed ,
I cant use the std ones from my old set of carbs as they are the early versions with primary and secondary main jets. So does anyone know what Keihin jet is similar to a #100 TK jet.
I think the pilots are drilled as well as one broke when looked at it :S
i think i can swap them with the ones in my old carbs

looking at that munted pilot jet even the air bleed holes look weird , corroded almost
