Kern Dog's got skills!! Looks awesomeWelded in is the way to go. Bolted can still flex.
I made mine, or more accurately, I modified 3x3" tubing. I cut it to fit the floor, wrapped it around the rear frame rails.
I also made my own torque boxes and welded it all in with the car on jackstands to maintain body weight on the tires. I primed and painted it all to look as clean as I could make it.

I seam sealed, primed and painted. I probably should have drilled a few holes in there just to let any water escape. I may go back and do that.Are you guys using a seam sealer after it being welded in or grind it down for the finish.
Damn I think I’m going to do the same, can’t beat $20 when if you buy them pre made they’re almost $200Made my own using 2"x 3" .120 wall rectangular tubing which I welded in place. Total cost was under $20. Unbelievable difference in chassis stiffness.

ITs hard for me to say if there’s a difference becuase I hadn’t driven the car in years before putting them in. They were an add on during my restoration project. I just know the car feels solid and handles well.Getxed do you feel the difference with the bolt in ones and what tubing size is the summit. I am guessing a 2x2 tube.
Glenwood was yours a kit or homemadeI used sealer up top only in case i created pinholes. Left the welds as it for strength.
