A Nissan parts catalog lists all the parts and their numbers. Perhaps 20% of 1200 parts are still available today from your local Nissan dealer, the rest are No Longer Available (NLA). The catalogs are available in three sizes: A3 (large) loose binder, A4 (standard book size) or 4x6" paperback (pocket size).
Datsun1200.com has all the 1200 parts listed here in the wiki by subject name, and includes Part Numbers for Japan, US, and other markets. Often they are compared with newer parts that may fit, e.g. from B210 or B310 or other Datsuns and Nissans, something you won't find in the Nissan catalogs.For example:
40160-H1001 (formerly 40160-H1000) fits:
- Raybestos 5051044
- AC/Delco 45D2044 (88911542)

Use the search box at the far bottom of this page to find them.
The catalogs were available in Microfiche -- a sheet of film with a document on it. They are A6 size of a postcard/photo about 4" x 6" each with several dozen pages of the catalog. So a set about 1/4" thick is the whole catalog. Use a negative viewer and magnifier to view it. So a regular paper catalog is better unless you don't have room to store it.
