I have an 05 T&C that I need to replace the motor and back door. anyone have an interchange list of vans that will work?

 

As for the rear door, any door from 01 to 07 will work but looking for what your trim is, this may make a difference on the looks of one, meaning with or without the chrome piece, badging etc. For the engine, through the 4th gen, many changes were done and for this, you in most cases need to go for exact year.
