Can someone please take a look and tell me if this is a 289 HiPo pressure plate? Didn't want to bog things down for dial-up folks (like me) so the pics are posted on this website: http://members.aol.com/dmgt350/cars/plate.htm It does have 9 green springs but any traces of a bronze paint daub are long gone. The plate diameter is 10-7/16 inches. Are there any other identifying marks/numbers that would be helpful? It came in a box of parts when I bought 6S1757 in 1987. The car had a very stiff competition clutch at the time left over from it's road racing days which I replaced with a Centerforce dual friction unit when the engine was rebuilt. Thanks! Dave
