My 80 has a good door on the DS but the PS is getting rusty and dented. I'm guessing that changes were made even though they all look the same, latch location, etc. What fits? Need a PS front fender too due to dents but I'm thinking those will all fit.

72-80 doors and fenders all interchange. The only difference I'm sure of is the very early doors didn't have the recess stamped around the door handle. Ma added it when a lot of doors cracked there. I think it was added sometime in either 74 or 75. It must have been important as it remained through 1993.

Cool beans!

72 are 72 only internals. The slider for the window/regulator are metal. 73 or so they went to plastic.

72-74(?) the lock knob sits in the door. 75(?) up Theres a grommet (noise/rattle reduction?)

72-74/75(?) door panels screw on. 76(?) and up, they pop on

That's all I can think of right now besides the indent around the handle.

Oh, seems 76/77 the key holes seemed just a hair smaller(?)


All statements based on personal observation/experiences and YMMV

All good stuff. As with most things, the right year is best. This gives me enough good info to go on the hunt. Thanks!

1972 doors have their own window regulator.
All 72-77 doors have the door lock button thru the metal.
78-80 doors use the plastic grommet around the door lock button.
72-74 doors will only accept the screws on SMC door panels and the sheetmetal door panels.
In 1975 the plastic clipped on door panels were introduced.
In 1976 the door handle recess was introduced.
Early doors had a bolt in window regulator. Later doors used rivets.
1975 doors are unique. The only year to use plastic clip on panels but no door handle recess.
1978-80 door use the push button vent window lock.

As a quick spotters guide:
72-74 doors are mostly the same but will only take screw on door panels
1975 doors will take any door panel and have no button grommet and no door handle recess
1976-77 doors have the recess and flip up vent lock, no lock button grommet.
78-80 doors have the recess, push button vent lock and lock button grommet.

Fenders have many variations too but all years will physically fit.
( antenna holes, and holes for items on the inner being the main differences

75 was the door handle recess introduction

75 Trailduster. My 75 D100 has the recess also

The 75 Club I traded you had them too when it had doors The 72 that those doors are on now didn't have them

I have owned 3 1975's and none had the door handle recess. My current original paint truck doesn't either. It may have been phased in late. I have an article previewing the new 76 Dodge trucks and it has a close up photo and describes the "new" door handle recess. I have collected 1975 Doors for years for my own trucks

Looked at my 75 last night, it has the handle recess and no bushing around the lock knob.

Forgot about this one too. Another 75 with the recess!

The 75 w100 I just sold had no recesses...

recess was my best subject but curiously was usually followed by being spanked by the principal.....on a positive note we were on a first name basis....

What about door glass? Did that change between the round roof and 80s square roof?

The vent window changed with the pushbutton lock in 1978, and then in the mid 80's the glass all got thinner. Not sure when the thinner glass came in but I think about 87. However it will all interchange between all doors if you use the related parts.
