Thanks. I will let you guys know what i find.
I was hoping that one company has different welding or construction techniques that are obvious when looking at them.
Ok you are all right. The Univair struts are easy to spot with the stainless forks and the U stamp clearly on them.
The other obvious difference is where the fork screws into the strut. The struts in my first post are Airframes with a very smooth appearance. The Unavair struts have a protruding plate within the weld. THANKS
