i accidentally threw a bunch of parts together in the same bin, and i also happen to throw a gsr and an si prop.valve in the same bin. now i can't tell which is which. this guy just bought it off me and i don't want to send him the wrong prop. valve.

 

I dunno if this will help but its worth a shot.
Item #4

P/N: 46210-S04-902

 

This one is for a gsr equipped with abs. I dunno the part number.
Item# 6 or 43

 

i have one in my hands right now from a 99-00 civic si
numbers on it are:
a 62 with a crossed out circle
8 S 1 with circles around it
and s29cE on one side

i hope one of those things help you

 

for people that know more than me.
