Julio Posted June 6, 2004 Report Share Posted June 6, 2004 I have resealed the LLC in doing so the rear seal falls out so I bought a new one, the old one doesn't appear to be bad but for the low price of a new seal one was ordered. Today I went to install it and they are quite different. The new seal is on the right with the green ring(see Picture) it is GM part # 12556107. The green ring is a metal band, the old one is all rubber. Did I get the right part? I thought at first this was some sort of protective cover for shipping but it doesn't come off. This is for a 97 Northstar if you have replaced your seal with one of these or know why they went to this OEM replacement please pass it on. Thank you, Julio Link to comment Share on other sites More sharing options...
