Trailer Hitch fab - threaded rods and nuts

NottaMiata,

Thanks for the levity!

Again, they're not for towing. They're recovery points. You screw a tow hook into them and a tow truck can pull your car out of a ditch. Almost all cars have plastic covers in the bumper to remove with a nut underneath to screw a tow hook into. 

I repeat, they're NOT for towing. Sure we can use them as such. But they have a well defined purpose. And one that's for quick gentle pulls, not for sustained loads.

Sustained loads gives way to fatigue in time. In order to do it safely it needs to be overbuilt.  
You would essentially need to reinforce the rear frame and crash bar. By the time it’s complete you just added over 50lbs if not more.  Our cars are flimsy in comparison to a real car. 

Hi thinking about adding a proper bike rack no towing for sure are these still available? Is there a step-by step install 🙂

Fast motion removal.

The fabricator is building a custom polished aluminum Grumman step van and starting a new business.   He said he had quit making these.  Not sure when he will make another batch.

I’m going to disagree with this.   Fatigue is a function of cyclic loading. Not a function of time.
