Here is the upholstery style of my rear seat.

Here is my front bench seat with center armrest.

I have a local upholstery shop who did my dash pad that can do the front seat any way I want. I thought doing the front like it is with black vinyl and black fabric would be nice, but then the back seats would be different. I could have him do it all in vinyl and match the rear stitching.
Then I'm wondering if anyone makes a reproduction cover for this bench seat that will match the original rear seat but in black vinyl?
