Thanks guys!
Did not know of the mount difference 67 to 68, as I have all 68's...
On the comment "The tracks with the plates on the bolts are 68 or later and the ones with out were 67 and earlier that used the loose carpet clip"
So the 68's did not use the "U" shaped "carpet protector" under the plate on the track originally, and those tracks as shown go straight on the carpet...??
