abandon project found...67-68 4x4

[too much stuff]

Got a call to go check out a 68 chevy shortbed 4x4 project that has been sitting for quite awhile. The restoration was started many years ago. Frame looks to have all been done, engine has been rebuilt, but been sitting so long it is froze up. He thought it was a 68, but all the clues i see look to be a 67. The original cab and vin were scrapped along with the glovebox door. Looks like this will all be parts. Can't imagine there were too many 67 short 4x4 trucks with a v-8. (if it is still correct.) The engine decoded to a 67 283 for pass or truck. Took 2 trips to get everything home.
Any way to say if it is a 67 or 68? I added the pic of the 2 leaf tapered springs in the rear if that narrows down the year.
Enjoy the pics as i know you all want to see.
