Looking to replace my stock steering shaft with either the flaming river or maximum motorsports one for more header clearence. Are they the same diameter as stock or a bit smaller. I need about 1/8" or 1/4" clearence from the header (1-5/8" mid length) and heard that these two are a bit smaller in overall diameter than the stock one. I wanted to make a dent in the header to clear the stock shaft, but dont want to damage the ceramic coating of the headers by heating it up to make the dent. Anyone have similar issues? Any info would help.
