1 7/8" tubing or 1 1/2" pipe?

Getting ready to rebuild a part of the previously installed "add-a-cage" kit the PO installed in my Jeep. Trying to figure out whether this thing is made out of 1 7/8"x.148 tubing or 1 1/2" pipe sch 40. I can feel the weld seam inside the stuff, but with it all painted up, can't see any markings of course. Thoughts on how to identify it beyond just a micrometer? Any telltale clues to either?

Also, near as I can tell, this thing was installed sometime between 1999-2001...

Have you cut any of it up? The wall thickness you stated would say sched 40. 1 7/8 hrew tube with a wall thickness more than .120 wouldn't be very common. If it is nominal 1.5 sched 40 it's probably heavy as a mofo...

It was very heavy compared to the 1 3/4" tubing I replaced it with. Since we were doing so much to the cage anyway, I replaced all the old stuff. Thank you for the response though!

Sorry, posted pics of the tire carrier addition on a separate thread. Here's a pic of the old cage with the tubes running down in front of the dash. Serious knee knockers...

Here's the new cage. Still have to add a few gussets and pull the cage to finish all the welding, and I hadn't started on the tire carrier yet when this pic was taken. Decided against the V tubes down the middle of the windshield. Eventually the A and B pillars will be tied to the frame, but for right now they just sandwich the tub with 3/16" plate.
