Wondering about the year of my truck????

[kyman]

So my truck title and Vin shows it to be a 67. It's a long bed/big back window truck. Originally was a three on the column. I now have a nice 355 and moved the shifter to the floor. What I don't get is this. It does have 68 front fenders on it due to the side marker lights. It also has 68 and later seat belts on it (figured that out after seeing the info on here). And the gauge cluster is not from a 67 either. Can't hardly read anything on the glove box door. Any help would be appreciated. And I work dark to dark ne,t few days, can't get any pics, but can look at stuff with a flash light when I get home.
