Just thought I would pass some info on!!  Just finished putting headers on our 55 Bird--   have Flaming River Rack and Pinion system, with their tilt colmum.  Put on Sanderson's--  They fit with out modifying anything, and really look good.  They fit over the steering col. then turn down . head pipe needs to be made--  but they are on the inside of frame without X member surgery.  All in all very happy with them.   Hope this helps someone!!!     God Bless
