Full parts catalogue — under construction
The complete OEM parts database (every part number, supersession, NLA status) is being extracted from the 1991 RM179U1 and 1993 RM285U manuals. Initial regex extraction produced too much noise to publish; a Claude-vision pass on the OEM spec pages is queued to replace it with clean structured records. The reference table below is what's been hand-verified to date.
