Thanks for all the nice comments. I'll try to answer the questions;
The speakers are Blaupunkt VX542 5-1/4" 2-way's. I have a pair of Kickers in the rear. The stereo is an Alpine w/Ipod controls in the center Tuffy console.
There isn't a way to lower the dash without removing the column, that's correct. But that's a relatively easy task.
The holes were hand-drilled. I've added some additional progress pics of the project so you can get an idea of what's gone on.
The knobs contol the heater and A/C. It's a unit I bought from Chuck at BC, and they helped me with the custom controls from Vintage Air.
I saw those Duff knobs as soon as they were announced and jumped on them and they look like they were custom made for my project! Just don't have them on the truck yet.
A couple of other points for clarity. I am not doing this work myself. I know that's a cop out to many of you, but the job was too big for me. I spec'd out the rebuild of this project myself, to the detail of a knat's ass. But the flip down dash and Bronco grill was ALL the idea of the builder. I can't take any credit for those, but I'll sure brag on his work! Most of the dash layout was taken from various pics posted from people on this site, especially Nick (Nicks Trix). That's why I like to post stuff like this, so others can get ideas and get inspired. I hope there will be plenty of inspiration when the entire project is unveiled! ;D
Thanks again for the feedback -- Scott
