fork seals

Hey, I'm looking at replacing my crappy old fork seals. I have my 33mm forks but after hours of searching can't find technical sizes for the fork seals or dust wipers :banghead: P.S. Any tips on fork oil weight?

I don't know the history of this bike...and I'm new to riding... Bike has some issues I am working through ... Just don't want to take any dumb risks... Seems to me like the forks are ok. Looks clean and shiny and bounce up and down... Not leaking .... But what do i know?.....Maybe the seals...
