Hi , I need 2 x base shims for a classic (1998) impreza. (They fell down the sink when I was cleaning th ehead .. I didn't even know they were there till it was too late.)

Starship Impreza very kindly sent me some, but I found they were the wrong fit.

The ones I need are like a washer with the "Lip" on the outside (as opposed to the inside).

This is driving me nuts so any help would be great.

Thanks - Mark
