Czechmans pics are incredible. If you want to see what a novice can do look here, I was impressed with myself! That is until it falls out after I painted the truck!

Here you can see the rust cancer which had eaten a hole through the inner brace and the outer hood skin.

Below is after I cut out all the bad metal and cut/formed a piece of metal to fit. I forgot to take a pic of that step, so you see it welded in already. Click next a few times to see the final.

Again, I am a total novice but thought I did a pretty good job. Just tack weld and let it cool so there is no warpage.

Good luck.
