I think I am getting close!
I am thinking its either this one: 51036-PV6

Or this one: 51026-PV6

Looks like it must be 29-31mm tape, but I am not finding it for sale anywhere. Or I am just bad at online shopping.
Maybe a combination of both.
I am finding the 51036 without the PV6 designation & no "adhesive on adhesive" bonding. Maybe I have to settle with 3/4" tape & just be happy its the correct material?
