Body part interchangeability!
 

Will doors from a 91 F250 fit on an 85 F250. I found a guy parting out a truck and wants $25 each for doors with power locks and windows! If not can the inside guts be used in an 85 door! I cant beat the price. Also the donor truck is an extended cab, will the front seats and console bolt up as well.

The doors will fit. I believe I remember there is a small difference in the area around the vent window, but it doesn't affect it fitting on the cab. I am not sure about the small part interchangeability though.

they will fit.. the differance is the vent window. like franklin said.

i'm not sure if the door panels will interchange tho

The door panels will also interchange as well as all the internal parts if they are done as sets. In other words some parts won't interchange without others being replaced at the same time.

Otherwise they are the same door with minor cosmetic differences. 1980-1996/97 and 1980-1999: F-600/F-900

The difference in the vent window is in the vertical bar.On 80-86 trucks,the bar is smaller than 87-91.This means that an 87-91 door glass is smaller in width than the 80-86 door glass.Also,the 92-96 vent window is different than 80-91.It has a section cut out of the glass to accommodate the dash sticking out further.Without this section cut out,the vent window would hit the dash.

Don't quote me on the 80-86 dates,because i'm not sure when Ford switched to the smaller door glass.My 80 has the smaller vertical bar vent windows,and when I replaced the door glass with one from an 88 F250,I found out the difference.The window is smaller,so it moves back and forth in the channel.

Ford went to the bigger vent window rail in 87. All doors are the same mostly from 80 to 91, there are few changes for the diffrent window parts, but a drill will make new holes for you!

It was in 1987 that the vent window and door glass changed.

The door shell itself remained virtually identical.

So with that information, you can swap out the vent window for a 1987-1991 as well and then the glass will work. ;)

But then it won't match.I'll eventually either find another 80-86 glass,or since my vent windows are getting rusty,I might upgrade to 87-91 Vent Windows and door glass.

I also have an 86 that i want to use the 88 power windows in. SO if I change the vent windows along with the door glass and panels ti will be a smooth swap, if I'm understanding right.

Correct.

Or you can use power window 1980-1986 panels with the switches for a 1980-1986 as well, as the electric motors are swappable too etc...

There are a lot of options with the doors. ;)

From what I seen on my 84,89 and a 90, the doors are the same for mounting window regs, you can keep the your 86 wide widow with narrow vent frame and be able to use the 88 power window reg. You will have to use diffrent bolt holes which should be already in your 86 door. And use only 1/4 inch long 7/16's bolts to hold it together(or rivits if you want) to clear the crank arms.

One thing that will make swapping out window regs easyer is loosen(or remove) the vent window and track, that will give you MUCH more room to move that pig of a power window motor assy around!
