Doors, glass, and seals

[D13]

I searched but couldn't find the exact answer I needed.

The doors on my 1987 are toast. they are PW /PL, uplevel trim. I have several rusty and/or damaged sets of 81-87 doors with manual regulators. I also have a 1977 with solid doors, manual everything. I'm making that truck into a lightweight machine. I'm looking at buying a set of aftermarket doors to put on it (lighter metal). These allegedly fit 77-87 (made by Key?).

So the plan is to move the 77 doors to the 87, install the 87 PW / PL combo in those doors. Then put the aftermarket doors on the 77 using 80's thin glass and regulators.

Am I correct that to do this the window seal set needs to match the year of the glass? And the most likely issue is the vent window package?

Thanks!

That sounds right, but I would verify with Precision Replacement Parts.
