Which Front Discs?

[eddb]

Hey All

OK - So I have a 1991 surf SSR X which I imported from Japan so I have no comprehensible paperwork. I need to replace the front discs, however according to the parts folks, in 1991 they changed the width of the discs from 18mm to 22mm. How can I tell which discs I need for my vehicle given the fact that I dont know what month it was built. I tried measureing with calipers but was measureing 11mm.... guess i really need to change them.

Thanks,

Edd

Look at the white lable on the seatbelt, it will tell you the year of manufacture of your truck.
