This page shows the sources and review decisions behind the measurements used by ExactFit. Evidence for the exact model is identified separately from verified equivalent-model or same-chassis evidence. Missing values remain Unknown.
Last reviewed: 2026-09-05. 2 retained source records. 0 unresolved conflicts. All inputs required by the cavity calculation are supported; an applicable cutout may replace additive requirements.
Counts use distinct measurement records. Left and right ventilation share one per-side source record.
Some measurements on this page are not supported by an exact-model document. Each affected row says where its value comes from.
Original published value and unit: see retained transcription below. Normalization: No separate conversion rule recorded; the stored normalized value is retained without additional rounding.
Confidence label: high.
