P1083 MGB Vent Cover: $10.95
Stay warmer and drier with this magnetic vent cover!
Cover will stop water leaking into your MGB, and eliminate that cold draft when driving in chilly weather. Also prevents debris from falling into your vent.
Magnetic cover stays put while driving, and will fit in your glove box when not in use.
Note: These work with original vent grilles. The reproduction grilles have less ferrous material in them and thus the magnetic attraction is greatly reduced.
