Absolutely correct on the 33 frame being totally unacceptable. In 1934, G.M went to independent front suspension. This style carried through into the early 50's. The 1948 Chevrolet and 1950 Olds kits have this style. As far as the frame, it goes from two straight rails to forming to the shape of the body. The frame would look like this LaSalle frame, only a different size.
I'm also single, retired and on a fixed budget. If you don't know how much you spend on something, it's your choice. To tell people that, because they know how much they spend for a build, they need a new hobby is only you opinion. Not fact.
I totally disagree. There are people in this life that keep track of their spending. It's their nature. I can tell you where every penny I spend goes. I'm an accountant and that's how I control my budget. It's got nothing to do with a hobby.
I use Gimp. It is a cross platform free software that is extremely efficient. Since I don't use Microsloth's windozs and use Linux instead, the procedures may be a little bit different. Open your picture in Gimp. Right click and select "transform tools", "crop". Crop (cut out) the picture to it's outside dimentions. Press enter key. Right click and choose "image", "print size". Enter size as needed. Press enter. Right click and in File, choose "export as". Make sure the extension is jpeg and going to the right folder. Press enter. Done deal.
But they are much less than yours. I calculated the diameter against the plug wires on my 66 Merc and the 30 gauge are perfect. I ordered 10' of black and orange Yesterday when I found the train website listed above.
Some new changes as I am using a single 4 bbl engine in my 59 Plymouth convertible project. The engine that comes in the 58 Plymouth is terrible beyond belief. AMT cut out details and fudged part sizes so that they could fit it into the engine bay. I'm using the 58 frame for the 59. The bell housing on the 58 is the same size as the 57 Chrysler. I knew that the 318 poly engine had it's own bell housing for the A488 trans. and had drawn up a mostly complete file. As a result, I printed out a proper bell housing, cast the 57 trans. and bell housing and cut off the trans to attach to that bell housing. Here's the result.
This is actually the best way to go about making this body usable. Back a few few years ago, I did a post that showed how to deal with 3d printed parts and the difference in types of printer. I built my own printers and used them as examples, but the principles are still the same. Here's a link to that post: http://www.modelcarsmag.com/forums/topic/101922-1935-lasalle-convertible-coupe-3d-printed-at-home-aug-30/?page=1
