Like that color combo, I had a 78 Blazer, a Bazzillion years ago, I decided to build mine in the same scheme. But mine has taken a backseat to some other projects. Thanks for the look outs on the firewall and the windows, tips like those are why I love this board!
Here is a picture of my 78....I think it was a 78, it's been a long time and I've owned lots of cars and trucks since that one. The one thing I do remember about it, it was impossible to get the interior warm. Nearly froze in it the 2 winters I had it!
