Rick,
Very, very kind of you to delve into my problem with so much effort and experience. Yes, pistons are true in bores and yes,they are Wilwood Superlite II's. Affirmative on the split rear Girlings and ventilated rotors. Thanks too for the website work and especially the part nos. Very valuable to me and I'll definitely investigate. Hope I'm NOT stuck with noisy pads after all this, but I'm becoming afraid you and Bob are right! Again, many thanks.
