That's pretty much the floor tub done next on the list is the sill.
now I searched hi and low for sills, doner cars would more than likely end up in a similar condition so that only left me one option, Mazda.
so I had the guy at my local mazda dealer fax me an exploded diagram of the sill arrangement and it didn't look like a full sill to me but to hell with it.
I waited four weeks for it to finally turn up and its no bigger than my two year old and at £150 I was a little gob smacked.
but again my pal (who does the sheet steelwork at a jaguar e type restoration company) took the sill and formed four copies from the original. sweet! so back to it. well the second pic shows the old sill and then the two welded together sections that will be my new sill.
