HELP! Two CST Trucks on eBay

[67_CST]

I have been looking for a 67 or 68 CST for months now without any luck, then today two of them showed up on eBay (a 67 & 68). Both of the trucks are in decent condition and both of them have split-bench seats. The 67 is a white longbed & the 68 is a green short bed. My question is, what would be a fair price to pay? Also, have any of you bought your truck on eBay?

Here are the links:

White 1967 CST Long Bed

Green 1968 CST Short Bed

At this point Im leaning toward the 68 because it is a shortbed and it is a lot closer. Also, I am curious about the difference in the value between the short bed and the long bed. NADA shows the value of the long bed trucks to be higher than the short beds... but my experience has been that the long bed sells for less than the short bed.
