There is a show this Saturday in Franklin Indiana, about 20 miles from me. I'm thinking about entering my NASCAR stuff. It would be a first time entering a contest for me.
When I did my Herb Adams 1973 NASCAR Grand Am, there were only about 3 published photos of the car. One of the original engineers/crew members on his car told me about the Petersen Archives. There were dozens of pictures of the car including almost every imaginable close up. I could not have done the car correctly without those photos. The same was true with my Buick Centuries. There were a lot of vintage photos there.
I'm calling it quits on this one. Not a great outcome. Paint fought me, chassis fought me. I had to remove and reinstall the engine, stance is not great but it is done, finally! Not my best work but looks OK from a distance.
I agree that this was an attractive car. My usual routine is to collect as many pictures as I can and measure and scale things out as well as get the shapes right. The bumpers are always a challenge to me. I am starting with the Monogram GS bumpers and cutting and pasting using them as starters. It will certainly take awhile.
I knew about the rear window and had not gotten to the quarter window opening. I also saw the front wheel well issue and have that pretty much fixed. Lots of compound curves and body lines on Pontiacs and Buicks. Very hard to model accurately!
Another idea I use for plug wire boots is heat shrink tubing. Cut it to the same length, put it on the plug wires and shrink it. It won't fall off after that and looks like an actual plug wire.
You can drill out the distributor center like you did and anchor the wires with a drop of super glue. I spritz it with ZipKicker to set them in before they can move.
You can also go to Hobby Lobby and look in the beading section. There are lots of different sizes and colors of beading wire. I use that for anodized hard lines and braided lines like oil lines.
