58 biscayne (4-door) - need help finding the right floor panels

hey there,
i just got me a 1958 biscayne over here in cologne. germany this march

now i desperately need some help from you guys because my floor panels do have big rustholes and i want to fix them with original floor pan reproductions. so here comes my question:

i find a lot of floor panels for the 2-door impala or bel air, but my biscayne is a 4-door(!).
Do the 2-door floor panels match for the 4-doors-cars, too?

Please all you late great chevy fans, please help me out before i order the wrong parts! thanx in advance!!!

here are some resources for 58 floor panels that i found
