OK, I dug out my RSS catalog and the part numbers that I used when ordering the items for my 54 were:
For the glass run channel (U shaped channel with fuzzy inside -mounts vertically and window slides up/down on it) - part # 8L, comes in 72" length
For the belt weatherstrip (cats whiskers) with stainless steel bead - part # YM3; without stainless steel bead - part #M8, both in 72 or 96" length
Clip that holds the belt weatherstrip in place on the inner window reveal - part # 2348. You'll need multiple, count your old ones. Take it from me, buy new, don't reuse old.
Staple that's used to hold the belt weatherstrip in place (attaches to stainless moldings) - part # 1999. Comes in a box of 100, should be more than enough to do the whole car.
While I'm at it:
For the Traveler/Vagabond rear hatch - rubber deck lid seal - part #4754.
For the 47-50K and 47-51F, the glass run channel part number is 5R
Hope this helps!
