Sorry guys I still like the 68 the best! Even though I own a 67 now.
To the OP just put 68 taillights on it paint the center body color, the trim argent and at car shows just tell everyone it’s a 67 1/2
As far as brackets there’s not much out there for use with the cast iron pump, I just sand blasted and painted mine gloss black. As for the engine 67-68 has to be red!
