Screw Protectors

There seems to be some confusion within the judging community and experts on the forums as to the correct screw protectors in the trunk of the ’70 Boss 302; in particular Metuchen-built cars. Can you provide pictures?

The pictures shown here show the correct locations and three different styles of protectors used by the assembly line. The gray protectors are used on the side marker lights. The rubber vacuum cap is used on the top inside taillamp bezel stud on both left- and righthand assemblies. The black hard plastic protectors were used on package tray screws and lens screws and are often missing. All three styles of protectors are available in reproduction.


Boss Caps

What is the correct radiator cap for a T-code ’70 Boss 302? I always see the “Dearborn cap” for big money on eBay. What is the correct assembly line installed radiator cap for my T-code Boss? A picture would be helpful so I can source the correct radiator cap for my Boss.

The correct radiator cap for a Metuchen built Boss 302 such as yours is the Autolite RS-12. The cap is Zinc plated with Autolite logo, RS-12, and 13# stamped in the top of cap. I have provided a picture of an N.O.S. cap from my collection so you can see the exact details you should be looking for.


Correct Antenna Placement

I have a ’68 GT convertible that I am restoring. It has the rectangular mount on the driver’s rear quarter. The person who sold it to me said it was the original placement. He had the quarters replaced in the late ’80s and put it back in the original spot. The front fenders are original and have no holes. I am redoing this car and want it to be as close to factory as possible. Any thoughts on where I should put the antenna?

The typical location for a ’68 Mustang antenna location is the right front fender. The antenna was shipped in the trunk of the car from the assembly plant to the dealer. In the antenna kit was a template to cut the hole in the fender. The ’68 OEM antenna also had a round base, not a rectangular base. The rectangular base was a later service antenna. If you are restoring the car I would relocate the antenna to right front fender with a correct-style reproduction antenna.
