got an 88 non-turbo vert with the dark blue crappy interior. does anybody make aftermarket blue carpet and what seats can i replace with the old vinyl blue ones? thanks...

 

The 88 vert only came with a cloth (standard) or leather interior (P package). The seating surfaces on the leather interiors was only leather... not vinyl.

And both carpet and new leather replacement seat covers can be found on Ebay

 

ACC (Auto Custom Carpets) makes carpet sets for the 2nd gen.

 

There is a place online that does front convertible carpet and front/rear coupe carpet called "StockInteriors" They do lots of other makes and models, and I haven't heard of anyone's personal experience with them. This makes me cautious, but their site seems all right.
