Hello

My garage door works, but several of the plastic hinges holding the panels together cracked. I can't find anything other than metal garage door hinges for sale. Does anyone sell these? And/or would I be better off putting in metal hinges, assuming I can locate the frame behind the vinyl?

I'm not looking forward to replacing these. It looks like the metal rails need to be moved before I can insert new hinges of this type in there. But I don't want to wait too long and be sorry when half the door crashes down on something :)

Thanks in advance.
