73-78 F-15078 R3 Illustration Supplement

11-16-2025 edited by Frank Swygert

 

This is part 2 of 2 parts.

Part 1:	73-78 F-14078 R3 Parts Catalog
Part 2:	73-78 F-15078 R3 Illustration Supplement

 

AMC divided the 73-78 parts catalog into two parts, the main catalog (numbers) and an Illustration Supplement (F-15078 R3). There are limited illustrations in the main catalog. The Illustrations Supplement contains 511 pages in one large PDF file, 78.6 megabytes.

The underlying PDF document is courtesy Greyhounds_AMX, from TheAMCForum.com, and his friend Rick. Physically scanning and indexing 2000 pages of 60-year-old-document is no small feat, and is a huge boon to the AMC/Rambler community.

 

About Groups

AMC classified all of the parts that go into their cars into Groups. Most groups are unambiguous (e.g. Group 1, Engine) but sometimes you have to get imaginative (e.g. speedometer calibration gears are under “Electrical”) (my interpretation: instrument panel gauges) or just memorize (Rear Suspension is in Group 11 with Springs and Shocks). On the whole it’s well done.

 

About part numbers

AMC and Jeep part numbers are almost universally of the form XXX-XXXX, seven digits, the first digit always 3. (e.g. 320 7888 is a hard to find transmission yoke). Occasionally a suffix letter. Many of the AMC parts dealers prefer to work with part numbers, since there are often many small variations of a part (e.g. transmission yokes) that otherwise look identical.

Here is a rough visual guide to AMC groups.
