It will fit, '73-'91 side glass, all the same, except for tint/no tint, but that's preference. I don't think tint was offered until late '70's early '80's
Seems there more demand for sliders than solid piece
You should be able to sell those sliders for more than the cost of the solid piece. I did this years back on my '78, I sold the pair of sliders for $180 and bought the solid pieces for $35 from a junkyard. I put those sliders in the local trader pub and the first person to call bought them for listed price (I was willing to come down $50), I had at least 20-30 calls on them for the 1 week the ad ran....
