FWIW, a few vendors have Revson molds and even NOS spoilers for sale. Call around. They are all fiberglas and do NOT have side pieces that flow into enhanced front fender flares. I have seen two versions sold as Revsons- the earlier is as above on some but not all the above posts. The presumably later version (that Peter Revson himself might not ever have seen!) looks like the early one but with a short splitter molded into the bottom for possibly better aero performance. I have an early one and like it because I find it attractive and it works well for its purpose but does not scrape the ground in turns, even on our modestly lowered '72.
