Model cars

I was wondering if anyone on here could point me in the right direction. I use to build real nice model cars when I was younger. I picked up a model that looks like my dads real 68 Dart that I helped him build years ago. I would like to make a model just like his car for his birthday.

What I'd like to know is (because I have been out of the loop for a while) what companys do you guys use for the best parts? I found some custom parts like resin hood and bumpers and some other add-on parts for what I want to do, but I dont know who has the best stuff.

Does anyone have any information for me?

Thanks
