So you need a Silvia interior? Because every 240sx, 180sx, and Silvia from 1989 to 1994 (1998 if you include the Kouki 180sx) had a S13 interior. They are all S13's, just depends which specific one you need. 240sx, Silvia, or 180sx?

I assume Silvia since you mentioned it in your post, but just wanted to clarify. BTW, what parts in particual are you looking for? They may be identical to US 240sx parts.
