40 SA is way too soft - the wear properties will be poor, even for a tough material like PU. Don't use an old part for reference because it will have embrittled. I'd guess 80 - 85 SA/D15 would be a more suitable durometer


Thanks, I was thinking it might be too soft also but had just enough of the 40 left over for the test piece. Was thinking it needed at least 60A. 80 is as high as they go in the easy to mix and pour formulation I am using so that it will be.

Thanks JD and Wesley for the photos. It looks like there might be a sort of finished lip on the outside rather than a taper. Can't tell exactly how wide that outside strip is but it looks like it might be a slight bit wider than the ones toward the middle -- sort of like the inside wide strip. I will work on that a little and have a small rounded downward extending lip to finish it off. Will also widen the rear tapered edge just a tad so the whole piece comes outward..

I didn't realize Joel had any sets left. Thought there was a mention last year that he had sold out with the poster that made the comment getting the last one but I must have confused something. At any rate, aside from the labor I think I can make mine for about half what I think the repros were going for. Since the repros would still be wrong not worth spending the extra unless these turn out to be a total bust. Would be nice if I had a tolerable 47 set to work with and have the correct things for the car.
