come on some one must be able to help
you might be better off taking some pictures of what you've done so far - the floor isnt double skined
the footwell should be double skinned
dont think all of it is but parts of mine are yes
i'm not on about the floor, i'm talking about the footwell. i know some of it is double skinned because i have drilled through it, cut it and welded it. think its the section below the pedal box. had not been modified or repaired it was as it came out of the factory when i had it. just a bit rusty. thinks its anearly 90 bulkhead.
