If you have the time review this thread from start to finish. This famous build "Project X" has to be the ultimate build of a 60 body on an 80s frame. Absolutely no stone is left unturned, no detail missed and is a great pictorial.
(if you're in a rush jump to page 6 to see where you need to chop the 80s frame to suit the 60 body.)
But be warned. Page 32 of this long, long build will break your heart.
