It's great to see you starting with the concept of drawing out your ideas in order to put together a cheat sheet.
I would use either and Old dodge ram frame, the older smaller style or a S10 frame. They are cheap and already have steering and brakes and make great rat rod frame rails. Plus in most cases you can buy after market headers and parts to fit these frames so that you do not have to do a lot of fabrication and this will allow you to be on the road sooner. If I can help, drop me a line
