You are looking for one of the most difficult, and rarest 2nd Gen. part...The elusive BB fan shroud. I was very fortunate to get my hands on a NOS one a while ago. I also sold a used one that I repaired last year. I had 2 that were damaged, and I was able to put one good one together out of them. I cut them each in half, and put the top of one onto the bottom of the other.
