Most exterior chrome will be the same as for a 1966 coupe.
The chrome trim on the top of the fenders, that runs from the front bumper to
the rear bumper, is unique to 1966 - and as a result, so is the chrome pot
metal piece that fits between the rear bumper and the rear qtr panel.
(altho, if you are getting this pot metal piece rechromed, you can grind off
the excess from the 64-65 pieces.
Gary Goers is a great source of Chrome to Body gaskets - just allow extra
time as Gary is essentially a one person operation. Contact info for Gary
Goers is found on the resource page of the online club home page.
Good Luck with your 1966.
