b17 vs b18a1 crank pulley

i was doing my timing belt today. broke the the b17 pulley ( who ever did it before me tighten the sH*t out of it. so i had to use my b18 pulley. i did noticed that the belt channels for the alternator, and the ac compressor is a little bigger in diameter than the b17 one. shouldnt be a problem right?

anyone have a pulley for a b17 laying around, thats in good working condition?
