Back to the fender saga!
What was supposed to only take a couple hours took a lot longer... I've read before that people have had to split the front of the patch to make it fit, but never both sides??? I measured a couple times, even compared it to the fender I have and all good. The contours lined up right... it just didn't "fit." Maybe it's because I wanted to use the smallest amount of it, maybe if I had used the whole thing it would have fit better (glad I didn't though).
This is why I like to use cut up longbed trucks for patch panels
So I got the main part welded up and left the PIA part for another day.
