Sliding windows help..(photos)

[L1ght51d3]

So the channels on my 75 rrc are rusty and I went to check if my parts rangie bits were okay with the intention of swapping them over but in the part's car the sliding windows and frame seem to be all one unit? And the latches are different So now I'm wondering if they will fit as I'd need to remove the entire side glass and frames

Any help appreciated as I don't want to remove them if they may not fit interchangeably as I'd want to out the old windows back in the part's car so it's not without glass as it's a complete car also

The windows changed in about 1981. The parts car windows are the later ones.
I don't know if they interchange but logically they will.

That would make sense as the parts car is an 82! I do hope they fit without issue
