BODY ALIGNMENT — Underbody (Cont'd) — Measurement Points
BF-55component photoUnverifiedThe coordinate-triplet text on the original page is very small (~6pt at 300 dpi). Values were transcribed from the scan as best as visible; some Y values may be off by a digit due to scan resolution — these should be cross-checked against the source PDF if precision is critical.
Underbody (Cont'd) — Measurement Points
NOTE
Underbody reference points A–M (upper-case) and a–m (lower-case mirrors) are marked at body shell mounting holes. Hole diameters vary by point (10–20 mm typical; 92 mm for the front strut tower centres). The coordinates listed below are measured from the X (vehicle centre), Y (front-axle centre line) and Z (200 mm below datum) reference lines defined on BF-52.
