Are you asking about BII windows? If so, the 84/85 window frames don't have the holes in them that the later trucks use so you'd have to drill those to use the later glass but is totally doable. The factory holes are quite a bit bigger than the posts attached to the window anyway so being accurate when drilling the holes is not super critical but of course you want to be close. Also when mounting them you need a bead of sealant and the nuts do not go on tight at all, basically just finger tight to hold tje glass while the sealnt cures/sets. I found that out after the first summer and my rear glass now has permanent waves.
Me? I want to replace my bolt ins for the glue in. I like the trim on the 84 rather than the rubber seal look on the later windows. If you were asking about your 05 truck I have no idea. Good luck!
