Hi,
You have options , pick one.
May get lucky by calling a few local boneyards(or stopping by),as 95’s-98’s are the same part, likely some yard would have a 6 popper, mostly parted out.. Floors are likely intact. Take & print a picture of your floor with the carpet up outlining what you needwit, go out of your way to make it easy for them.
These folks you want to be overly friendly with, lol, they can do a lot for you if you’re ever in a pinch, or make your day miserable & expensive.First few cars I’d built I learned that.
Of, you can just get come 14/16 gauge sheet metal & roll up your sleeves. A little time, .patience goes a long way.
They also make universal floor pans. Not exact. But close.
Good luck!
