Window Difference Between early/late 60's?

[ProwlerDriver]

I was looking at SOR for new window felts and they list that they are not available for the 80-86 60s but are available for the 86-87 60's (not the 62) is there a difference in the windows? will i be good ordering them anyways- mines an 84. Thanks for any insight!

I wasn't aware there was any difference at all.
