Got the tail light panel DONE today! Everything went well... a little 'too' well, it seems. Had me scratchin' my head for a little while wondering what I did wrong - but I can't find anything wrong... so BONUS!
Here's the corner patch after 'blasting and getting it all welded in. Fits like a glove!
Then, after lots of measuring, and even using a bottle jack and 4x4 underneath the weatherstripping channel to boost up the left side about 1/4", it's all in.
After getting the trunk lid put back on and lined up, I used it to help line up the panel (as Scott advised) - which helped immensely. Also cleaned off the yellow grease pencil from the junkyard and decided to make it a 'Mach 1' again - Sharpies Rule!
And finally, popped the quarter extensions on and lined everything up. I'm not saying it's perfect, but I think I can be really happy with how it came out (with proper alignment of the extensions and everything once the new quarters are on, that is).
Now, it's just a matter of getting the new wheel houses in, so I can change out the quarters. Hopefully, I can get them here by next weekend. If not, I still got bumper brackets, the latch, and the gas tank forward strap bracket to get done.
It's all starting to come together. It's weird... but 'good' weird.
