I need to tow a small boat with my 1948 1/2 ton. I'm sure the truck will handle the load except for the brakes. I've seen many posts and advertisements for front disc conversions. Question: Which is the easiest to install and get working quickly? All current brake components on the truck are new. It looks like the truck has non-stock 15-inch wheels with stock brakes. I know that I might need spacers for the front wheels.
