Setting camshaft pulley timing for timing belt replacement?

1998 Plymouth Breeze 2.0 automatic, timing belt broke, pulled it all apart, ready to replace. Found mark on crankshaft pulley to set cylinder #1 at TDC, can't find any marks on Camshaft pulley face or gear teeth or head near case. How do I set correct cam timing ? Have valve cover off but not sure how to set it by looking at valves either. ?!?!
