Firewall Insulator Spacers
These 1979-1993 Mustang firewall insulator spacers install into your Fox Body's firewall to keep your A/C Heater box in place. Made of plastic, these spacers clip into the existing holes and the heater box studs slide into these holes for a durable mounting. Over time, these clips can become broken or go missing causing your A/C box to rattle and sag. This kit includes two spacers to get both studs mounted perfectly and securely.
