Hi CoopDeFeet, welcome to Talk Morgan!
I started with the instructions on this thread, and I think truckin-on is referring to something like this light plus bracket set on Ebay:
https://ebay.us/Vk7GspYou can also find stand alone brackets like these
https://ebay.us/Lh75L3, which is what I bought, although I didn't use them in the end.
I ended up simply mounting mine on a piece of bent steel bar with holes drilled in it, as I don't think you need to mount them as high or wide as trucking-on did if you don't have his badge bar.
I found some vintage 5" round German-made fog lights very much like truckin-on's on Ebay after a lot of searching, and converted them to LED bulbs. Still not happy with the color you get with white bulbs in them, it is too lemon-yellow, so I have some amber-yellow LED bulbs on the way from China currently.
