As for the seats & tracks, up to '77 for sure. GM changed the rear floor in '78 and created a footwell for rear passenger and the flip & fold rear seat was intro'd.
However the same style of flip up front seat ran all the way to '85 I think. The tracks changed too but not sure when. Maybe after '81...

The buckets themselves were the same as in pickups but the tracks were different. Low backs were gone by '77 or '78 as well and only high back buckets were offered.

The console is pretty much the same from '70 thru to '80.
The early ones had squares for seat belt buckles. Think it was '75 or '76 they went to a round holder for drinks. That stayed thru '80. The early ones had an emblem on the lid and that was gone in the later '70s versions.
In '81 they were redone for the new interior and sheet metal upgrades.

Pretty sure I got that all right...

Yup sure did.
And it seems up to 79 , pass seat and rear was an option
