troy, if it wouldn't be a problem can you post a picture of those tracks. 68 drivers side is locked to the front. Thanks
Hey Bryan, welcome to TC...
FYI- You replied to a posting from 9 years ago, which was a reply in a thread started 18 years ago! Many posters are likely no longer on this site.
As someone mentioned above, 71-72 buckets came with a slightly different kind of tracks that had a latch on the inside track as well as the outside.
All 66-70 buckets only had the latch on the outside track and the inside one is just free to slide.
I don't have any photos to share- the tracks look the same, except the inner track will have a short locking "arm" in the middle of it that points to the center with some holes in it for the actuating rod, where the outboard track has a larger lever arm that sticks out the side and a smaller arm on the inside with holes for the actuating rod.
Since the 71-72 style were only used for 2 years they are much rarer to find. If you have 68 seats, you most likely have 66-70 style tracks.
Its very common for the tracks to freeze up. Take the seats out lube them up with wd40 and work the slides back and forth until they move freely.
If they move freely unattached- they will move free in the car, unless the seat is installed crooked which jams the tracks.
