OK, I took some photos today of a 1968 Dash that I have in my garage. The 1969 gauge pods are the same. I don't know how many photos I can post here, so I'm just posting the link. To view the photos please go to my photobucket site, thats:

Let me know if you still have any questions after viewing the photos. Also, the speedometer cable is held in place by a spring clip, you can see it in the last photo. You press in on the clip at the 6:00 O'clock position and pull out on the cable. John
