What are you looking for, stock, aftermarket? The sport wheels IMHO look the best, but are getting more difficult to find at a reasonable price. Take a look on ebay to get an idea of what is available and going price.
As far as stock steering wheels, I think the '75-'77 looks the best, and many Fords from that era had them. If you want an original '73 steering wheel, any from '70-73 Ford or Mercury will work. Just check the junk yards, or ads for cars being parted out.
I imagine all the old plastic steering wheels in So. Cal. are sun baked. They are around here and there in northern regions. What color are you after?
I've got a few Ford sport wheels that I could recover, both with and without finger grips. Check out my work: http://mmb.maverick.to/resources/ford-sport-steering-wheel-leather-new.232/
Depends on the model you want, horn emblem, leather and thread color. Prices start at $300. PM me if you want to talk about one.
I found a fake leather wrap wheel...simulated? I dont know what, but it was already unbolted so it came home from pick and pull with me. From a late 70s or early 80s van or truck.....I was in the truck section.
Lol....relative to what I have it is nice, but I have seen pictures of your handiwork and it qualifies as beautiful. The wheel I picked up has the horn terminals, but I will need to use my cracked, glued, and painted horn cover, or whatever its called.
