I just put a set of leather Flofits in my car. I also purchased the rear seat cover from Seat Source. How difficult is replacing the rear seat cover? Is this a job I could do myself with simple shop tools, or do I need the services of a professional upholsterer? Specifically, it looks like the rear seat 'uppers' are pretty simple, and only held in place with the ever present Christmas tree fasteners, and a couple of listing wires/rods, I think I can handle these. However, what about the lowers? If anyone has tackled this job or has some insight, your thoughts would be greatly appreciated. If it is simple, I would be willing to purchase a set of hog ring pliers and some rings, if that is all it takes? Thanks.
