There is a 39 ford frame on craigslist in Escondido CA for $600.
Lacks the centre bracket but otherwise looks in not bad condition.

Might seem like a long way from CA to Ontario but I've bought them a lot further.
Among the good things in the southwest is the low rust factor. I've been challenged out her as parts that we enjoy plenty are described as "thin on the ground" in many areas. We also enjoy an active car culture that makes the preservation of our old cars more practical. Driving the old cars not as lovely while the leadership thinks that we should be on bicycles and is taking needed traffic lanes away in a war on the fossil fueled vehicle. Too late for me to relocate now. Good Luck: Fred A
