Completely false. 1.25" rotors were standard on 73-80 (or 81) trucks, 81+ typically had 1" rotors...some may have had the 1.25" units. ALWAYS measure when ordering drop spindles, it could cost you big $$ if you guess or assume.

No sweat man...the whole "what size brakes do I have" comes up at least once a month around here. Just trying to spread the word.
