Well...in that case I'm all
I'd have to guess that mine is older, and you have a newer, redesigned c/member...
Mine was purchased by PO too....and is back to at least 2003/4 AFAIK.
I did get a replacement about 2 1/2 years ago after dropping the c/member right on top of a rock...
...and they sent the same "Unistrut" looking piece.
But hey....back to the bottom line..
...it aint required anyway !
