Anyone know where I can get new rubber seals for all firewall openings? Steering colum,clutch rod,master cylinder,heater hoses,break lines...ect.
Check with one of the large Mustang vendors. They should be pretty much the same. Do a Google search for "Mustang parts vendors"
Mustangs have the same plugs for a lot of the Maverick stuff. Steering column is Maverick specific and you can get at Auto Krafters. Clutch Rod: Auto Krafters (I think) None needed for the master cyl I don't think anybody makes the heater hose grommets. Nobody make the brake line grommets. If you need the firewall plugs for a factory AC car to cover up where the non AC heater core was located.......Cougars use the same plug up on the cowl.
