I think that Jim was saying to ask about getting a carpet made for a 4 dr. Hardtop. Now, to jump in (because I'm not familiar enough with 58's), I bought a carpet for a 4 dr sedan for my 55 wagon and it fit perfectly. Ok, not perfectly. You DO have to trim around the back seat braces. The wagons in 55 were just scabbed roofs on sedan bodies.
