I can't begin to describe how much I like this K5
I have always LOVED the plaid interiors. It's very refreshing to see people taking the time to revive them (or accurately recreate them as you did) rather than pitching the seats and installing basic LMC-type covers or going with another type altogether.
I don't think SMC used to have the fabric in stock. Maybe they did and I just didn't ask the right questions. Oh well, making a thousand mile drive to get plaid seats in my trusty old Burb is a trip that will always be remembered.
I'm curious about the dash pad and door panels that you had refreshed. Does it look original around the screw holes in the door panels and does the dash pad have the correct looking center speaker opening?
