I just bought some flat stock at Homo Depot Cut 4 pieces about 3.5" long and drilled two holes two inches apart ,a few nuts and bolts and about an hours time . Two inches makes a big difference . I did it so my elbows have a little more room by straightening my arms more plus at 6" tall a little more leg room don't hurt either . Didn't know about the premade ones but I do like knowing I saved about 60 bucks .
