I can hear the groans already.
So just a quickie - have been reading all day and am still confused.
Can any part of the dual exhaust system including floor pan and rear frame rail reinforcements, brake pipe support brackets be used to identify a factory GT ? or can these be had by other option routes ?
Car is 1965 April 13R Dearborn fastback.
Everything else checks out, just wondered if any part of the exhaust is a pointer.
Thank you
