Regarding the distributor problems that have recently surfaced on the site...
In 1957 Chevrolet went to a new design distributor, and kept it thru the 1974
models
when they switched over to the HEI distributor. Wayne gave you the lead to
Parts America,
and they show the following when you go thru the motions: Listed for both 1956
and 1955 V8.

This is the 1957-74 design, and uses a tall cap with 4 screw head
hold-downs, and is adjustable while the engine is running - a great benefit
when tuning the engine. If you are going for originality, you are going to
have a problem - those vacuum advances were hard to find 25 years ago when I
was really into the 55 Chevs. The NOS parts had the diaphragms rotten from age
- the off-shore replacements were trash. A good used one was gold.
Unless you are restoring to absolute original, the '57-74 version is the
way to go, and this is a good price in my book. Any wrecking yard should have
a bin full of them for a core, depending on how much "core charge" is asked
for. Actually, unless the shaft moves excessively or the advance mechanisms
are rusted, the wrecking yard ones are usually fine "as is". Put in a new set
of points, rotor and cap, suck on the vacuum advance to see if it moves the
plate, and stab it in, run it and forget it for 20,000 miles (point life).
