So I found this on eBay... I asked him if it's for the manual or automatic, and he said they will fit both transmissions. I'm sure they will bolt in there, but from what I've seen on rockauto.com and gmpartsdirect.com and other places, they are different part number... Any thoughts? http://cgi.ebay.com/ebaymotors/04-08-Ch ... 141wt_1165
