Well, they're in!!!!
Probably wont get me a gig on the latest hot rod TV show, but I'm happy.
If I had the truck torn apart and could stand in the engine area I would change the whole panel. I have created some work by sectioning them in place, but I needed to prep for paint any way. If I was to install the whole panel, one thing I would do
before cutting out the original would be measuring the original gap for the windshield(the space that it fits in from top to bottom). This panel may try to re-establish a new line and I dont know if it would cause trouble re-installing the windshield or not. The corners are the hardest to deal with and the rest of the panel is a breeze. If you drill down thru or up thru the panel you can lay the heat in pretty well as you have a double lip to weld against; it doesnt move! One problem with sectioning is the joint against the original metal; welding on to the old stuff blew some holes but I just kept at it and got it done.
I will fill in some small places with weld and then it's on to the fiberglass and seam sealer, prime it and sand, sand, sand.
The end gaps down low are no worse than the factory, BTW.
