1984 GPZ550 FORK SEALS

Hi guys, here I´m again. I´m looking for the front fork seals for my ´84 GPZ550. I can´t find the OEM ones in Argentina, and the only official dealer needs time and soooo much money to get them from USA (same old, same old, you can look at my brake pad post...)

I know that sometimes oil seals come with a code number indicating outside, inside diameter and thickness. Kawasaki part codes are: 92093-1154 and 92049-1089, but these numbers mean nothing to my local auto or moto parts dealers, and in the parts list in the Kawasaki website they don´t specify measures...

Maybe some of you guys know those figures, so I can buy the seals PRIOR to disassembling the forks, which is my Plan B (going from shop to shop with my seal samples until I find the right ones

Cheers
