Dallara floors

Anyone know if the rear floors for the F397 and F398 are interchangeable?
Yes. However, some floors were for wide track rear suspension, and won't fit a narrow track car. Your car was narrow track I think.
Other than that, they should be the same in every way. The floor wasn't upgraded for the 1998 season.
