That's interesting. Part # E2TZ 7005-A doesn't show in the MPC that I have on DVD which is from 1994, but I'll bet it does in the 1982 version I have on microfiche. There's a note on the box for the one on ebay that says "RB E4TZ-D", which is MPC-speak for "replaced by E4TZ 7005-D". And in the snippet from the 1994 version, below, you can see that part #.
But, that part # is for the front half, and what is shown in the pics is the rear half. So the note should have said "RB E4TZ-
C".
Is there any way he is going to get $285 or more for half of a case?
