Rear window help quick
 

At the junkyard and need to know if the back glass is the same in the 150 and the 250?

I actually found one in a 250

Yes the back glass would be the same in a '72-'93 - 150, 250 and 350.
They came as a solid one piece version and with the slider window option.

I had the slider but the seals between the sliding windows were gone. I decided to go with the one piece I guess
