Car went through Mecum Kissimmee back in January. Described as retaining "the matching-numbers 396/375 HP engine and matching-numbers 4-speed manual transmission feeding a 4.10:1 rear end."
Description also said "Extensive Eckler's receipts included" (not sure that'd be a selling point, but at least describes the restoration).
