Frame Connector Question?

$50? Mine were $8 a side! I bought the 1X3 11G steel rectangular tube by the .lb out of the metal supply scrap bin. Cut, welded a front butt plate at the end and tied other into rear subframe on the 65. I can jack up the car behind the front tire and the rear will come up the same height as well as the door alignment not moving at all even when opened. Couldn't see that without them installed. I tacked the bar every place I could into the floor pan, about 5 places but couldnt stitch the entire length as the floor is not flat and I didnt want the bar to enter the interior.

$9 A SIDE FOR MINE , 2X2 SQUARE TUBING AT WHOLESALE STEEL YARD.
Welded plates on the front of tubing to bolt on while welding , cut floor boards to fit tite , installed ''inside'' of the rear frame rails and welded /and plug welded also , welded floor fully , welded up front plates / left the bolts in , fitted 3/4'' foil sided/closed cell house insulation ''board'' to flatten and smooth out the floor boards inside to make floor perfectly flush before new carpaet, cant ell it anywhere but underneath . Probly about the stoutest way to do it , full length floor welding adds a bunch .
