If they are like the ones I have looked at in a junk yard they look good. But as ssba said above, only bucket tracks that will fit without any modifications is A body bucket tracks.
I once used a set of Furd Exploder Tracks (forget what year) mounted to a set of Eagle Talon Buckets. The exploder tracks were close to the shape of the A-Body Tracks and I believe I only had to bend the front mounting ears/tabs on the tracks a little bit to mount up to the A-Body Floorpan.
