A customer brought in a 1937 Ford that his Dad had worked on over the years.  We cleaned up the distributor contacts & discovered that Dad had done an upgrade so that an universal coil could be used rather than the old type that was built into the old distributor.   Good idea.  Originally this car had mechanical brakes & not hydraulic brakes.  Dad upgraded to hydraulics.  He also added brackets (excellent welding job) & regular shocks, but left the old lever shocks in place in case someone wanted the original set-up later. Obviously a man with vision.
