Are your pedals in the forward most position? If so your problem is that the links to the rudder pedals aren’t long enough. Their is a thread about this but long story short, you can buy two pieces of thin steel from Vans and fabricate 4 new ones longer. Having longer pieces allows the pedals to be in a more vertical orientation preventing one tube from hitting another.
Are you sure that the correct tube is in front. The spacing from tube to tab is different. The forward tube has a longer spacing than does the rear. Someone posted a while back some issues and their tubes were reversed.
If thats not the case, pm me a photo or send me your e-mail and see if we can figure it out. I can then e-mail a photo of mine.
