Front Glass channel felt?

I bought some from Partsmix:
Mopar 1967-74 A-BODY, 1966-70 B-BODY, VENT WINDOW CHANNEL (Pair)
Part# 2202896
Yeah It was a PITA to get the window out and the whole frame at the same time. Im sure its going to be the same issue getting it back in after I replace everything. Any advice would be great!
