So I finally find me a crestliner wheel. Get it and notice that, 1. the splines are gone and 2. somebody cut some of the back off of it, and 3. its a little ruffer than i thought it was. My question is can it somehow be re-splined? What can i use to rebuild the parts that were cut off? The black wheel is supposed to look like the white wheel. If you look in the last pic you can see the crack, did a search and figured out how to take care of that. How can i fix the sun damaged brittle areas?
