Cant find timing mark on crankshaft

Refer to diagram for timing marks.

There really is no such thing as top dead center anymore on this vehicles anymore. If the timing has been disturbed for any reason then you would need the special tools to lock the cam and crank in there correct timing position to install the timing belt. At this point you may want to take it in to a shop that has those tools and after have a compression check or cylinder leak down test to make sure no valves were bent while it was been cranked over? Hopefully you were not too far off. Good luck to you and hope everything works out.
