I'm looking at enhancements for my '40 wagon, and since it will be getting a heart transplant soon (230 engine and power pack setup) from a '56 Plymouth, I started wondering what other more modern technologies would be transferrable to the old girl. The '56 has power brakes - I don't think the original is in good enough shape to use, but I wonder if there are aftermarket vendors who sell "universal" power brake kits to boost the old drum brakes?
