Sliding door windows are the same from '80~'84 (early) and from '85~'91
(late).  The early and the late ones will NOT interchange.

All the other windows are the same.  That said, Westy sliding windows
(both sides) are different from the passenger vans but their frame sizes
are the same.  Their frames conform to the previously stated early and
late years.
