I'll try to get pics in the next 2-3 days for you. The colour is VERY close, in the time that they have been on no one has said anything not even my wife!
No modifications required, but if you've never done upholstery work before you'll probably be scratching your head a few times trying to figure it out. The only thing I had to do was cut holes in the sides for the armrests to attach to & holes on the tops for the headrest posts. This was a little never racking but actually very easy & looks great.
I did add thin pieces (1/2" maybe) of foam to each side of the drivers side lower & to the centre. My seat foam was in pretty good shape, adding the foam pieces just helped to add a bit of support & fill out the seat bottom. I did the passenger side first & did not add any foam, I'll be redoing that one. I didn't need much foam and wanted it to be firm, I tried a few things then ended up using a piece of foam flooring, the kind people use in basements, garages, workout rooms etc... Some spray glue helps hold the foam pieces into place & also to hold the seat heating elements in place.
No bacon smell to report.
