Well I already had the tubing in house machined for the seals... but didn't feel like fighting it.. just ordered it with the tubes pressed in..KWTMECH said:It is actually cheaper to order with the tubes already pressed in. Figuring the cost of the tubing and fighting with it and pressing it in. Just figure out the width you want ahead of time and order that way. Never heard of them ''having to put the ends on'' . I usually order them without the ends on and add a couple of inches to the tube length.[for final trimming if I need it]
