65 Barracuda daily driver

I've been working a lot, so haven't been able to work much on the car. I did install these back-up lenses that I got from Mexico. Unfortunately the quality of them is quite poor, they are a bit smaller than the originals and I had to use longer screws to get them in there. The outer red ring that is supposed to have a reflector is just concentric circles. I wanted to use the original reflectors, but they won't fit because the clear lens is too small. After all they don't look so bad and they are an improvement compared to the cracked old ones.

That's how cracked the originals were:

And then I attempted to swap out my old crappy Monroe shocks for some used KYB shocks that I bought here from a member on FABO. Unfortunately they are one or two inches to short and so they won't work. Also, one of the upper shock mount nuts was so rounded that I could not get it off. I guess I could just remove the entire upper mount from the interior. Anyone know who sells replacements? At least the nut, but maybe just the whole thing?
