I would recommend a couple of spare rubber bushings (not sure of the correct name) for holding the rectifier and exhaust in place. With my car, one that was holding the rectifier split in two and those that are keeping the exhausts in place are looking pretty tired. I haven't yet found a source for replacements, although I managed to get a similar sized one for the rectifier (but I don't think that this would suit the exhaust as it is a few mm larger).
