We found that the "feet" attaching the firewall to the chassis were rusted through in places, so the rusted bits were cut out and replaced with small, welded-in patches. This was "fiddly" work that required a lot of patience.
Also one of the "toe panels" was so badly rusted that it was not useable, so a new one was made from scratch. This was also quite fiddly work as it is a double thickness panel with lots of bends and angles. The yellow one is the original panel and the red one is the new mirror image copy. All the bending and folding was done in an ordinary vice, as we have very few tools. We have not done this type of work before, so it was a steep learning curve and some things have had to be done twice

before we get it right.
