Also going to ask for some pointers as how people would best tackle the rust at the seat mounts/ seat belt mounts, and round the body mount struggling to get the grinder in :( verging on going to be a compressor and a small air grinder!
My plan was to cut the whole seat mount out and reweld it onto the new metal, also, for doing the floor in the footwell, am i better to shape this or is using just flat sheet fine?
Anywhere, here are the photos:






So yeah, any help would be appreciated!
