My timing belt broke while I was driving, what is the process to find tdc and line up the cyl heads, the manual I have only covers replacing the old one.

tdc/camshaft alignment

It seems like all the repair manuals on this subject, deals with replacing the timing belt, and thats fine, but:

They dont say anyting when the timing belt breaks while driving, and what the process is to finding tdc and aligning the camshaft gears.
can you help with this?

thank you
