Just ordered a Gasket ring from Anayama for my Prelude Import but the gasket ring is too big.
Part no:18393-SH3-S00
It’s out by 3mm any suggestions or has anyone got one spare to sell.
Thanks.

Got a couple of them here - here is a pic of it on a jdm cat. it does sit proud but i guess it is supposed to so it crushes down to make a good seal. I dont have my calipers at hand but can get them tomorrow if you want me to measure up the dimensions.

Dimensions look spot on, if you have one spare how much would you want for it inc shipping.
