Really nice condition, no pitting or cracks. The passenger side has a spacer which was used in later 68 - 69 model years but lots less trouble for your '67 than the original '67 - early 68 thermostat valves were. Date codes 6J6 and 6J19.
$395 for the pair including shipping in the 48 states. If you live anywhere else let's talk via PM regarding shipping costs.
