I did some measuring tonight and the drivers door from the mounting point of the guide to the inner structure of the door is 5/8 difference from the passenger door. I believe this door is a 71 by the milar sticker that was on it, just cant remember if it was early or late build. i'm seeing lots of different info, some say the 70 is alone and some say the 70 and 71 are the same and the later ones are different but only the glass is different. They make repop guides just not sure which ones i need. I can not find any in and out adjustment for the glass at the bottom when it is rolled all the way up, the bottom adjustment moves the top in and out but the bottom is fixed.
