X 2 on SMS...
I actually had mine completely rebuilt from the frame up by a local upholstery shop. The guy who did them was in the business over 30 years, and retired not long after he did mine. There was enough of the original seats left to use them as a pattern, but that's about it. The drivers side of the front seat was just totally gone...as in metal frame was showing. The rest was really rotten. I've got some snap shots I took when I dragged the car home, but I still haven't had time to scan them...I'll post them when I do. The seats in your car actually look pretty good compared to what I started with, but you're right...they could use some help.
Just for an example, here's what mine look like:


Hmmm...thought I had a better picture than that online. Guess not

. Oh well, gives you an idea what they look like anyway. If I remember correctly, it cost me about a grand to get both seats completely rebuilt. They're actually pretty comfy now too
