It’s on a 72 f100 ranger xlt. My father in law said the truck came with beefier rear suspension and a 360 engine. Is this a camper mount? Or was it for antennas? The truck is 100% original as his dad (the owner who has since passed) was into modifying his trucks.

This is the best pic I have of it.

 

Not factory, probably a radio antennae bracket.

 

Yeah, I was thinking it was a CB antennae mount too.

 

Gotcha, thanks guys! Is there an easy way to tell if the truck does in fact have a beefier suspension?

 

Yes, easy as getting a Marti report...at least if it came w/ heavy duty springs from the factory:

...a well spent $18 IMO.

 

Would that "HD" suspension be the Flex o Matic?
Look at the rear spring bushing area. Does it have a cantilever arm built into it? That helps push down the spring, effectively shortening it and making it stiffer with a load on.
