hey everyone i want to install my door cobalt ss aftermarket door sills that I got for my car but I have one question? do you tear off the old rubber stock door still or do you put the new ones right over top of the old ones? the reason why i ask this i because the instructions that were left by MRZ Performance were not very good. I personally dont think they go over the old sills but the instructions say too in n indirect way(as much as that makes sense hahaha) anyone out there installed these door sills and can give me some advice please! Thanks
