Nice valve covers,I believe those covers once belonged to Tom Debartalo. I believe the guy you bought those from, I sold a set of new T&D rocker stands to. There is one set left of billet covers that were never used to my knowledge .. he is or was a member here,the guy in Australia that used to run drag week with a silver Predator headed drag drive car. as far as I know he never use them, might do some foot work if someone wanted a pair. I still do on the program for these if I was able to sell five sets, I could have more made
