1996 Toyota Camry Timing Belt

Engine Mechanical problem
1996 Toyota Camry 4 cyl Front Wheel Drive Automatic 160K miles

In my haste, I forgot to mark the position on the original timing belt when I removed the water pump. Stupid me. If that wasnt bad enough. The crank and cam were not positioned to any timing marks prior to removal. I do want to be clear though, The cam and crank have not been moved at all since the removal of the belt and the timing was fine when I took it off. So How do I go about putting a new belt back on this? I can post pics if needed. This is the single overhead cam type with two guide rollers, one being spring tension type. Please help! Need my car back. Wife is agitated. Edit!

I just received a response after I paid but it seems like its not clear. If I put a new belt on, how do I know if I'm not skipping a tooth? In order for me to turn the engine to TDC, I need the belt ON in order for both the crank and cam to move simultaneously. My thought is to at least put it on to the best of my ability now, then manually turn the crank until some marks are lining up. Then fine tune from there. If possible, I dont want to open the valve cover and distributor, is this ok?
