I saw them during my hunt for new rear shocks since I apparently have worn out shock mounts, and the Suncores is the alternate brand I saw popping more than anything. The one thing that boggled me for a bit was gas shocks as opposed to air shocks. I suppose it's all the same.
In the end, as I'm figuring out myself, it seems more cost effective to do as Low suggests and buy the T-Bird shocks with the mounting hardware.
