Posi rear tag, red 1" on fill plug, repro?

**KevinW** · #1 08-09-2023, 09:17 PM

So I have this red plastic posi tag for fill plug. I have been told a one inch hole is for corvettes. I need one with 3/4" hole for my 12 bolt. No clue on how I got this, I never owned a vette.

But is there a way to tell repros from originals? The adhesive on the back lead me towards repro, but I figured I ask here. thx

Kevin, I believe the originals had a period after the DIFF.

68-69 Camaro looked like this. Notice it says "Positraction" and does have the period after "Diff."
