Installed 2/3 of my aspec kit (rear and sides) a few days ago. I am looking to replace some of the fastener clips and spring nuts. All of the nuts have either rusted and broke apart or on the verge of, and some clips damaged. Can somebody recommend sizes or specs that will fit? The dealership prices are ridiculous. They won't tell me the size or specs.

a) big fastener clips - found on front and rear bumpers, also on side skirts. ( looks very similar in size as the 10mm bolt holes)

b) spring nuts - found on side skirts and rear.

c) small fastener clips - used to fasten the trunk interior trim.

Will the local auto parts stores carry these? I've also seen some on ebay.
