Rubber floor mat/covering

[RollinSlow84]

I'm looking to build my Malibu into a 60's style stripper model and I'm looking for a rubber floor mat to cover the entire floor instead of carpet. I checked most of the well know aftermarket places but haven't found what I'm looking for.

I'm wondering if anyone has done this or found a place that sells something like this. ANy ideas on what other cars have a similar size and layout floor pan.

Thanks.
