I'm not real good at decoding and especially 68's, but I'll still give it a whirl.  If I screw it up on you, I apologize.
Center front seat with folding armrest (buddy seat or mother-in-law seat)
Bucket seats
Outside right hand manual mirror
Outside left hand remote mirror
2 watt AM radio
Sport wheel covers
Tinted windshield
White vinyl roof
Then you have some codes for the mouldings and eninge, transmission, and axle (2:76?).  You also have a scheduled build date of May 18 and an SO number of 152318, which should correspond to numbers on your rad cradle and trunk lip under the weatherstripping.
Howzat?   Remember, no promises on the accuracy.
