Wrist issues are pushing me towards making a welded Surburban Machinery type drag bar with WAY less pullback but I need to know what inside diameter/wall thickness tubing to use. I know that O.D. is 7/8" and I used my calipers to measure 1/16" wall thickness and 11/16" I.D. Can anyone confirm wall thickness and I.D. I just want standard bar end plugs to fit. Thanks in advance.
