INM in Guadalajara would not extend his 7 day EXPIRED FMM tourist card because there is no "tramite" (processing) to do it and would not issue him a new 180 day tourist FMM card in Mexico, only at ports of enter do they issue them to foreigners entering Mexico.
If he was at any INM office before it expired they could have extended it for him another up to 173 days for the $500.00 pesos payable at any bank and then bring back the paid reciept paperwork to INM..
