1964 FJ 45 back window panel

[wilkie]

I am trying to rebuild 1964 FJ45 (long wheelbase ute) that was used as a parts car.
I bought a back window panel that was from a later model.
Are there any differences between a 64 back window panel and a later one ?

should be the same if it is a removable hard top up to 84..
