HELP...putting my Wing Vents back in and have ?s

[DrtyJack75]

I've got a few questions for the ALL KNOWING 67 Owners.

When I bought my truck the PO started putting one-piece windows in the truck. He did a ****ty job so I'm going back to the wing vents.

If someone can answer me a few questions:

In the LMC catalog P.19

38-6390 Vent Window Assy - LH - Clear 68-72 $209.95
38-6391 Vent Window Assy - RH - Clear 68-72 $209.95

QUESTION - WHAT IS THE DIFFERENCE IN A 67 and 68?

QUESTION - WHAT OTHER PARTS DO I NEED?
# 9 Division Bar w/felt 38-5891 $29.95
# 10 Window Post Liner Set 38-5955 $29.95

P. 16

I believe I need:

#3 Window Seal - Inner 38-5961 $19.95
#4 Window Seal - Outer 38-5963 $19.95

Anything else ya'll can recommend me getting?
