Made from 4130 chrome moly seamless tubing with 4130 tube weld nuts. They ave 3/4" QA-1 right and left hand rod ends and all grade 8 hardware. They measure 19.5" center to center but can be adjusted either way. Super nice product! Have been 1.35 60" with these. $200 shipped. I will take paypal or money order. Thanks, Cory
