Here's the ones I have. According to the parts book, your '69 GTS should use the top ones which are 2449932. The center pair are 2841393 which they show as being for a 4dr sedan. The bottom one is 3613923 which came out in the early '70's. The early ones have two pins on the back and looks like they can either press into a socket clip or fasten with speed nuts. The center pair use a screw to mount them and have a centering pin to keep them straight. (one of mine is missing that pin). The bottom one is designed the same way but the pin is slightly bigger in diameter and about a 1/4" longer so it would probably take either type of fastener like the early ones along with the center screw.
Thanks, Mark
P.S. Oh, and the bottom one is almost twice the thickness as the other two.
