drain plug gasket size?

[LOST]

im prob gogin doing my first oil change on my gts this weekend, does any1 know the size of the drain plug gasket for the 3.8?
thanks

it's 14mm lost, btw the drain plug itself is 17mm

why thank you :-)

the only reason i asked is I have the 04+ galant techincal service manual, and in the oil change section it states to replace the drain plug gasket with a new one during an oil change. I really dont want mitsu voiding my warranty over a 1$ gasket

BTW, did you get it from the dealer or an auto parts store?

well, i live no where near a mitsu dealer so i had to go auto parts store, basically i just got 1 so I could get the recipt for a gasket so my dealer couldnt give me crap about a doing the service myself.
The gasket that is factory, is different than the one's sold at auto parts store, well at least advanced auto; so the next time ill order it from the mitsu dealer b4 an oil change, besides im following the standard service recommendation but i didnt want to use the facotry dino goo and oil filter to 7000miles, so i swapped it out for mobil1 and a k&n oil filter
