I have my mechanic looking for new brake lines for a 2001 2500 sport was wondering if anyone had and place they use. Was driving home and blew a brake line and realized all of them in the engine compartment were severely rusted. also i have the same problem as everyone else with the driver and passenger doors fully rusting on the bottom and i have a body shop to cut and reweld them but was wondering what the best option to seal them is after i get the body work done. Thanks people.
