G'day... I've been offered some doors off a '71 Beetle for a pretty good price.. Are they gunna fit my 64??

I know that windows changed size post 65/66, but were there any other major modifications?

Any knowledge mucho appreciado.. :thumb

They will fit, or I should say the door and hinges will bot up, the catch won't fit the 60's latch on the body and will have to be changed to the later ones.
They will also look crap as the windows are bigger on the late doors.
Just get the proper doors.
