Thanks Keith!
Thats all I need to know. I'll get the engineering works to fill it in again when I take it for sandblasting next Saturday. Thats assuming I have got a 'donor' piece of metal by then. I have an acquaintence with a few Ford CMPs and a good oxy torch.
I didn't give a moments thought to saving the floor plate screws. Some were damaged, some were fine and some were already missing. There is a fasteners supplier in Gympie where I can buy new ones. I bought samples Saturday.
The getting of new weld nuts seems to be quite a trick though!
I'm awaiting return emails from 2x manufacturers with prices.
