Unfortunately, the market for the 1967 body style is very soft. I only know because I'm a big '67 fan and have taken a hard look at your cars. The most recent '67 GTX to have bids on eBay was item 112815311005, a red 440/auto car that was only bid up to $20,200. Even if you look at the last (10) '67's that sold at Mecum, they're pretty-low priced.

$37,000 - silver 440/4 speed at Kissimee 2016 (impressive car, high bid, no sale)
All of these cars have their idiosyncrasies, but the '67 market is, overall, very low. With your automatic car being the non-original color and your 4 speed car being not-quite-finished, you might be looking at the low $20,000 range.
