  "limits": "Manufacturer CZJ542/CZJ543 applications and supplier product photographs establish folded connecting sheet, ramped sides and unequal opposed openings. All numerical sections, 13mm access radius, 2.54mm gauge, ramp contour, web station and extension are construction estimates. The 6.25mm receiver radius and all four pivot axes retain the old drawing references. Catalog handed positions are recorded separately; exact handed pressing and installed access-face clocking are not recovered. Photographed base holes and square apertures are not copied as an unsupported drilling or weld map. The rail/pocket, wishbone, bush/pin/head/washer/nut, spring and upper platform sources stay unchanged. Source contacts and gaps do not establish actual weld ownership, bolt engagement, loaded rubber, strength, alignment, tool access, safe support or a verified replacement path."
