Bucket Seat Tracks '68-'69 vs '70-'72

If anything I'd believe just the opposite is true. My 68 came with 71 buckets and I feel like a little kid sitting in his dad's car. (I'm 6'-0) I'm seriously thinking of adding spacers under the tracks.
I may have a definitive answer soon as they are coming out to do some floor pan hump work. I have 68 seats I can compare them to but it may not be in the next few days.
