Topper glass questions

[nocoasthardcore]

Hello all,

Silly question for anyone that knows, is the K5 topper glass interchangeable across all the model years? My rig is an 89' and I am going to be changing it over to full convertible. My parts tuck is a 74'. It has no glass and I would like to use the sliding privacey windows from my topper. Any help would be greatly appriciated.

from what ive been told by the local body guys here, is that u can put newer windows in the 74 but u have to use the window seals for a 74 or it wont work, i know this because i have a set of sliding glass windows for my 74.

Thank you for taking the time to respond.

On the 74', are there different seals for sliding and non-sliding glass? Also, what year did the windows change? Or did the seals themselves change somewhere along the way?

i do believe the seals changed in 76, but sliding windows werent an option in 74 to the best of my knowledge so if u can find a set of seals for a 74 they gotta be right
