Body/floor/interior rivets and rivnuts

[jps]

Merci beaucoup for taking the time with a comprehensive answer, much appreciated! I'll take a much closer look through your blog now, the photo's you've got on there are very helpful. Although I am hoping that I do not have the mysterious gaps in bodywork I suspect I may have similar challeneges ahead, as my bodywork has been waiting to be fitted for nearly 3 years now and may have adopted some new shapes...!
