I have just called around to eight different vendors with the same response: the manufacturer is having difficulty stamping out the part after they finished the initial run a couple years back. What does this mean to us...they do not know when they can expect to get more stocks on hand. Heavy Chevy did tell me that they would contact the manufacturer to find out if they had any "get-well" date on the horizon. I will repost when they call me back.
Sorry for the bad news.
