  "limits": "Factory Parts-1977 PDF p72 illustrates upturned channel edges and elongated inclined mounting openings. It does not calibrate the cradle. Selected24mm lip height,6mm inside bend radius,3mm gauge and9x18mm slots are construction estimates. The two repeated channel edges are a reconstruction interpretation,not a surveyed CHA266 pressing. Existing outline bounds,base bearing plane,fixing centers,gearbox pad faces,rubbers,fasteners,crossmember and source transforms remain. No fitted identity,slot adjustment range,drilling map,hidden attachment,weld,loaded support,tool access,clearance or replacement/removal path is verified. The common engine/body frame and earlier static source contacts remain unresolved;no neighboring material is cut to force fit."
