The Ace parts are not going to work for me, they're way to small for the factory or FFP vent.
What I'm looking for is a suitable replacement for the factory vent push in nut.
The dimensions are M13xM18 outside with an M5-0.9 thread.
This is basically a sheet metal blind push through fastener.
A ford part number would be great but it's not available separately.
I would like to keep my stock vent and get new fasteners for the replacement.
There seem to be very few sizes available and none with M5 thread.
