Antenna Delete Plug for NB Miata

Antenna Plug and Locknut for an NB Mazda Miata. The hole in the rear left quarter panel (on the '99-'00 for sure, cannot confirm on NB2 cars) is about 1" diameter. This plug is a .25" tall protrusion, and has a groove for a #119 o-ring for sealing against the fender face.
