Big Bore Shocks - End Cap Part Number

[Shuntfield]

When I built my shocks, I put the bladders in. However I have now swapped the one car to the o-ring instead of the bladder in the end.
Unfortunately I cannot do the other car as one O-ring is missing. U3667 doesn't contain the o-rings only the bladders. Can anyone tell me what the part number for just the o-rings will be?

Thanks

Thanks.
I did see that but I don't have the vented caps but still if that's the right o-ring then happy days :thumbsup:
Cheers!
