what size of weld on end bushings does everyone use? 2" ? cause or will 1 1/2" work? im using a 2x2 bottom bar and 1 5/8" top bars. are the 1 1/2 too small for that purpose?
Just remember that the measurement includes the bushings, which are 1/4" on each side. So 1.5" would have a 1" wide tube to weld to. I used 2.5" bushings on my 2x2 bars and the weld on tube was the same width.
