Hog Ring size for FJ40 (1977)

[Jumpseatin]

so I'm doing some work on my front seats and noticed a lot of the cruiser places are out of the hog ring and plier kits. I saw a cool dewalt one that automatically loaded them but wanted to know what size hog rings are on the seats (I don't know how to measure them). Anyway, does anyone know the OEM hog ring size on the bucket seats by any chance?
Thanks in advance

fyi an offset pliers is really handy for them as well.
don't know the size off hand...i'd guess .375" or .5".
