Here are part number for the V6/350/455 oil pump thrust plate. Pioneer OP-20-I Clevite/Dana/Perfect Circle 601-8030 Melling P-20I Dynagear DP20I Muskegon MP20I Federal-Mogul 224-518TP Also attached is the blueprint or drawing for making one. One of the scans I have is for full size, but is too big to upload if anyone wants it. Cheapest price I found on-line was $11 for both the Fed-Mog at rockauto.com and the Melling at advanceauto.com I don't believe this is the same as the booster plate as there a modification to be done to it but I believe it only involves grinding a slot.
i just picked up a melling one from advance today . along with a pump kit . had to order it of course .called on a sunday afternoon , had it monday once i got off work . no shipping :TU:
