Sure, it is done all the time, very easy usually. You just make a 337 that says you discovered this and than, and it meets all the requirements of some approved information. I had to do a stack of them like that to bring my coupe up to proper paperwork, radio, transponder, intercom, wheel pants and more. That said, read Ed's post carefully. I too would if it were mine, remount the avionics and re install the header tank. Solves LOTS of problems I think.
