1. I can get you in touch with a guy that will sell you a whole used spindle, brake /strut assembly for fairly cheap for the 87+ 5.0 cars with teh bigger rotors. I was thinking of going that route with mine.
2. You can get unpainted sfc's for around 75 bucks nib shipped. I cant remember where I got mine I think it was 50resto.com
3. Strut tower brace. Check with 50resto on that one too or shop around online. there are a ton of places that sell this stuff, so it can be had pretty cheap.
If you want the guys number or need any help shot me a pm
