Explanation of Catalog Conflict: ARI 17-77525
The discrepancy between the two results is caused by a duplicate part number reuse conflict in the historic database layers of American Remanufacturers Inc. (ARI).
The 17-77525 part number routes to two completely distinct mechanical parts depending on the catalog year:
1. The Early 1980s Domestic Catalog Line (General Motors B-Body)
In the original vintage ARI indexing matrix, the suffix 77525 was assigned as a direct cross-reference to the industry standard number 53-2725 / 577525. This maps to the GM Delco-Moraine single-diaphragm booster. It services the 1985 Buick LeSabre, Chevrolet Caprice, and Pontiac Parisienne.
2. The Late 1990s Import Catalog Line Expansion (Mazda MPV)
When major parts suppliers updated their databases to keep up with late-90s imports, Cardone and ARI reassigned/expanded the exact same 53-2725 identifier to map to an import dual-diaphragm setup built by JKC/Aisin for the 1989–1998 Mazda MPV. [1, 2]
What this means for your inventory box:
Because both fitment matrices share the identical 53-2725 interchange blueprint sequence in chronological automotive parts indexing history, you must verify the physical unit:
If the physical booster inside your ARI box is a large, thin 11-inch single-diaphragm stamped steel unit with a flat domestic mounting pattern, it fits the 1985 GM vehicles.
If the booster is a thick, dual-diaphragm 9.7-inch unit with metric studs and Japanese manufacturing marks (JKC or Aisin), it fits the 1989–1998 Mazda MPV
