Locking Gas Cap

OK, for a 69 Cougar, has anyone installed a locking gas cap? Can you please revommend a manufacturer/product. Trying to find a reliable, keyed OEM style cap that fits the cougar. Gas prices are making my tank very desirable here in Chicago… :wink:

Thanks everyone…

Stant has always made good locking gas caps.

I think Stant is the brand I had way back when. As I keep my Cougars in my locked shop I am now running factory twist on caps.
