66 2 door post front and back are the same length
66 2 door HT the front is longer
66 4 door front and back are the same on lower models for sure, upper models like VIP not sure
Depends on what model of car you have and what model of car they come off of. 65/66 Fury I And Fury II Use the 9" front armrest pads. 2 door or 4 door. Fury III Sport Fury and Vip use the 13" Armrest pads. 2 Door and 4 door doesn't matter they use the same pad accordingly.
