There is a difference. I got a call the other day from someone that got my door handle kit with my fiber gaskets. These are thick paper fiber gaskets made out of the original material just like GM used. He questioned why he didn’t get Rubber ones like everyone else sends. I said the rubber ones stick out from the doorhandles and when you tighten them up, they squish out. Plus they rot within a couple of months. I take the rubber ones out and throw them away and add my fiber gaskets to the handles. No one else has these fiber gaskets I sell them by themselves for 995 on my website Www.qualityclassicparts.com
