Best source for reproduction parts?

[duk007]

I recently bought a 66 chevelle, that will be a pro-touring build with an emphasis on track time more than show time. The car is currently a roller with a new but not show quality paint job. I'm going to start to put it together while I decide on some of the more important parts of the build. I need to buy some of the not so sexy parts, exterior trim, windshield, interior panels, ect...

So my question is: From your experience , where is the best source for such parts? Year One , Original Parts Group,Classic Industries,someone else ???

Are they all the same part just different distribution ?

I've seen as much as a 25-30 percent differnce in price for the same side view reproduction mirrors from several reputable vendors.

I value quality, and want a good fit, but don't care if it's not an original gm
part if there is a good alternative.

Thank you for sharing your opinion.

Keep in mind this is never going to be an original 100 point Concours type car. My plans are to do as much track time as possible and still take the family out for ice cream on Sundays.
