Bill, as you can see by getting no response, you have asked for the Holy Grail of used parts on a TR4-4A. All have cracks by everyone using the wheel to brace themselves getting in and out of the car. You can have them dipped and they come out pretty good. I think I saw a place in Hemmings that does it.
I have one I fixed for a friend and he is humming and hawing about the price, let me see what he says and I will get back to you.
You might want to ask what one is worth with no cracks. Not cheep. I have one with cracks if that is the way you want to go.
