New Mustang

[Mustang[RIP]]

Hi all,
I have been a happy Mustang owner for about 5 years I have had a 95 Mustang 5.0 Convertable and a 97 Mustang that was pretty cool.
Anyway I just bought a 1967 Mustang inline 6 and I plan on doing something with it but I'm not sure what to do.
I have had a couple of cars in car magz but they were VW's and it was when I was 20 years old so I have worked on many cars for years.
I have the drum brakes on this car and I want to put 4 whell disc brakes forsure so what I was wondering is does anyone know where I can start buying parts and what are some of the better places to buy from.
I am in So California I am close to saleen on of my fav cars I was going to buy on when I bought my 95 but my wife and I couldn't find so we looked at the Cobra and on the test drive my son barfed all over the only Cobra on the lot so we past that one up and got the Convert GT.
Well if anyone has any ideas please let me know I have alot of work to do to make this car the way I want it and I know it will take me more then a year to do but I feel like a kid again so this will be fun.
Thanks,
Bob
