Well, the cow-meter goes to "10" when these straps are placed anywhere near the sensor :-) I have a bin-full of original black ones with the smaller diameter d-ring. They also appear to have a vinyl insert. We unstitch the ege holding the d-ring in place, replace it with the proper larger diameter d-ring and sell them. Alternatively, for the few black interior cars that have the strap mounted in the door, these can also be unstitched to remove the d-ring and used on those cars as well. I agree with James about the difficulty in locating the grey leather. Bridge of Weir no longer makes that color/grain, and despite repeated attempts to encourage them to do so (read: $$$) they are not interested. We've since located a company in Spain that is not only doing the color/grain to match, but also creating the unique grain for the vinyl as well. James Espey
