A 68 KR that I purchased in the 80s was frequently dragged race and came with the usual modifications: scatter shield, no power steering, console removed, Hurst shifter, and these "beefy" vintage traction bars.
They can be yours for ONLY the cost of shipping, PM if you are interested.
Look like Lakewood's to me.
They don't look like my old Lakewood bars. Look at the location of the snubbers and the offset on the back end of the bar also.. Lakewoods were much nicer. These look like they were possibly home made bars.
