Started on the lower section tonight. It will be done very similar to the top half so i started making templates but before cutting out the old section i made one piece first just to make sure its something i can do. I didnt want to cut ot the old stuff and realize its a bit out of my league and be left with a huge hole in my firewall.
Here are some pics.
Getting my templates


After i cut it out, i'm left with a flat piece of metal

And after an hour and a bit of beating, folding, stretching, more folding, more stretching and more beating, Wellah.



And just a pick of it sitting on top of the old stuff in place.

It still needs a bit of tinkering but i'll do that when i cut out the old piece, like i said, i just wanted to see if i could do it first.
Cheers for looking
Benny
