Differential Filler Plug Tag
 

What years/what applications used the fan shaped tags that said "USE LIMITED SLIP DIFF LUBRICANT ONLY" vs. the ones that said "USE POSITRACTION DIFF LUBRICANT ONLY" ? Paragon says 66-72 used "POSITRACTION" and 73-79 used "LIMITED SLIP." D&R says "LIMITED SLIP" is correct for 69.
Which style would have been on a 69 Camaro 12 bolt?
