Is this Cobra an Arntz?

If it does not have the safety cage around the passenger compartment, it is a Type I
If has the safety cage and door impact beams, it is a Type II
I can see from your pictures that it does not have the drip edge molded into the body on the hood opening for weather stripping, so it is not a Type III

Unfortunately, it's not that exact. There were parallel lines, and some with different build cycles and features. Like this one, some from G&R Engineering (originally here in NorCal Sacramento) and a few versions later on from Paul Bennett with updates. Having worked closely with seven different Arntz, G&R, Bennett versions, there was more variations than consistency. Some w/wo roll bars, or rear tri-bar setups, others with different body features and flare types, yet some cars with later updates that started out as early cars.

When I went to Ron Butlers place 15+ years ago about a project, there were 4 different types there on racks, some back for updates and changes, suspension swaps and more. No debate in any case, they are a unique and cool car.

Recently helped a friend pick up his 3rd Arntz a few months ago. Good fun.

Enjoy!
