Thanks gents. .095 is .1lb per foot lighter than .120. Won't be enough to make any kind of difference in weight but I'd venture to say .095 would be strong enough too. Its only .0125 thinner per side. My PRP seat sliders are even smaller on the OD, not sure on thickness.
Yea, I don't think my PRP's frames are even 1".....

I have done 1" x .120. Or just mounted off the main x members. I prefer the latter, because no extra tube needed! Plus, with the 1"... if the tubes get too long, my fatass can flex them a little.

The reason I picked the 1" x .120 was because I have lots of it for building bedside mounts, etc. If I were to do it all over again.. I would probably get .095 for all that stuff..... And save a whopping mcqaurter pound with cheese over the entire truck. LOL

Yeah I could drop a big deuce one morning and save the same amount of weight hahaha. I put my calipers on the PRP seat mounts and they are .75" OD. I'm sure 1" .095 will be fine

As a follow up to this, would it be ok to plate the body where the new seat tube welds to? Rather than cut a hole in the trans tunnel and connect both sides. I have an Atlas transfer case down there that may be in the way hah

Is the rest of the cab caged? I would try and run the seat tubes to the floor tubes of the cage.

I think that would be fine.

I originally welded the front seat tubes to the tunnel with a 0.065” doubler plate on the trans tunnel. Then I decided to make the ugly hoop that goes over the tunnel as well.

Rear tube goes all the way through.
