The second thing I noticed was that I have two different spoiler end caps on my car: a long end cap and a short end cap. The shorty with the white underside is the original 70-73 endcap (PN 480159) and the black undersided, longer tipped, end cap is a replacement from a 74 to 78 T/A (PN 493688). At least it's easier to trim the longer one to match the shorter one. Thankfully that's a lot simpler than trying to make the shorter one grow to match the later longer, end cap.
