What type of ladder bars are these???

Those are sweet as all get out. Probably been on there 30-plus years.

I was running a '70 Z in 1971, and I could bake those F70-15's at will, only headers away from stock. Like everyone else back then, we were screwing slicks onto the rims for strip use (J/Stock Automatic), and pretty much everyone was running slappers of some configuration or another, mostly the widespread designs available speedshops. If there was a "sticky" tire back then, it was out of my affordability range.
