I've been working on removing the carpets from my 164 in order to dye them to a non faded colour. I haven't found much on the process of removing the carpets as most have to do with they dye part then the removal. I have worked out the carpet but I'm stuck with one last part. Beneath the accelerator there's a metal stopper plate. It seems that it's held there by a nut from the backside bracket. The only problem is, I can't figure out a way to get any tool behind the plate to loosen the nut. Anyone know if there is a trick to this part?
