I captured these as HTML files years ago that I've had stored for many years. I'm putting them here for future reference. It came from corvettemagazine.com digital format. It's title was: "Name That Distributor" by Alan Colvin. It was a article describing the different distributor applications.
Note that it may not format perfectly as I merely did many copy/pastes to get it here in this thread. I was unable to get separate images in the article as I couldn.t retrieve them at the time.
Note that there were no 1956 or 1957 reference pages.
I added reference to this thread in the Database of Restoration Documents Sticky..... UPDATE Page.

The Delco-Remy Division of General Motors in Anderson, Indiana manufactured all Corvette distributors from 1955 through 1982. There were two plants involved in producing ignition components at Delco-Remy. Plant 10: All conventional (point-type) distributors and ignition coils were built at Plant number ten while all ignition amplifiers and capacitor discharge ignition systems were assembled at Plant number six. All HEI ignition systems and the newly developed (late model) Direct Ignition Systems were assembled at Plant number twenty.
Delco built a variety of distributor component combinations that were used from 1955 through 1982. All distributors were of cast iron construction until 1962 when the die-cast aluminum 4- and 6-cylinder models were released. There were "Bowl" and "Non-Bowl" distributors produced in both aluminum and cast iron. Early distributors had an external oiler tube for routine lubrication. There were also "Bowl" type cast iron units that had special two-piece housings with dual-point breakers inside the distributor. Because of the numerous combinations that are possible, please see the distributor application list for your specific application. We do know some specific combinations used for Corvettes. For example, all Corvette distributors produced from 1955 through 1974 were cast iron and all were equipped with tach drive from 1962 through 1974. In 1975, all GM cars, including the Corvette, went to the HEI ignition.
Distributor Model Number and Date Codes
All Delco-Remy distributors have a model number and a date code system either stamped or attached to the distributor. There are four basic locations in which this information can be found which vary from distributor to distributor. On all 1955-56 distributors, the model number is found on an oval Delco-Remy tag riveted to the outside of the distributor housing. In the 1957 model year, the identification process began to change. From 1957 through 1974 all cast iron non dual-point distributors used a small aluminum band, which wrapped around the top of the distributor. All 1957 through 1961 dual-point distributors used the oval Delco-Remy riveted tag. This band was imprinted with the model number and production date. Fuel injection distributors from 1957 to mid-1958 used a Delco tag identical to other distributors. Starting in mid-1958, the fuel injection distributor was redesigned and was produced with a square tag that was held to the main distributor housing by four screws. Late model aluminum distributor housings have the model number roll stamped right into the exterior of the housing with no attaching tag of any kind. Date code stamps are near the model number. The location varies from year to year. On early distributors with a riveted metal tag, the date code is above the word "Serial."
Date Code Deciphering
All Chevrolet distributors use the same Julian code system date code style. The actual build date is signified by a series of numbers and letters. Example: 5A28. The date code is deciphered as follows:
The first digit gives the calendar year of production. This is the last digit of the calendar year, 1955 in the example above. The second letter indicates the month of production. See the table below for month codes. ("I" was not used because it is too easily confused with the number 1.) The final two digits indicate the day of the month of production (1 through 31). The code 5A28 therefore decodes as january 28, 1955.
Distributor Color Coding
Most distributors installed at a final engine assembly plant had a color code applied to the distributor housing. This was to enable engine assemblers to identify a distributor without reading the code number. In time, many of these paint marks wore off. Most Delco Remy blueprints call out these color codes as paint spots.
Distributor Applications
The charts on the following pages list the distributor applications for 1955-1975. All distributors are in numerical order within each model listing. Each distributor is listed by model and engine, and then further distinguished by housing type, point type and other features. Be sure to check the model years before and after your car to check for other uses. The abbreviations used in the charts are listed below.
