I didn't see a sticky on this but think it should have one maybe. I am going to be replacing them in my 98, on rockauto, there are listings for a 2nd design. What's the difference? I hate mail order parts, but for the price, worth it as long as i receive what i need. In the pics on their page, they all seem to look alike... So what's the 2nd design all about???
thx in advance
