Kevin, I just took a mild steel THDP off my car. There is nothing wrong with it I just found me a polished stainlees steel one. My old one does have two extra bungs. one under the turbo for egt probe and one down low for a/f sensor. They both have screw in plugs in them now. $250 and $35 shipping.
If you'd like some pics. pm me your email address and I'll take some for you.
