The stock-design and stock-length descriptions state 321mm and 335mm respectively. Treat those as product dimensions to compare with the installed shocks and replacement references. Do not infer a single factory CB450K length, unchanged ride height or matching clearance solely from a stock-related product name.
The 290mm eye-to-clevis listings give a 12mm ID × 21mm upper bushing, but not the lower clevis opening width or bolt diameter. The separate eye-to-eye version states 10mm ID × 21mm bushings at both ends. Confirm the actual mounts and required clearance before ordering a custom set.
Compare the shocks fitted, the listed measurement method, both mounting ends and applicable replacement references. The two families state different lengths. Their stock-related names do not establish which length matches an original or previously modified 1969 CB450K.
The mounting layouts differ. The eye-to-eye version specifies 10mm ID × 21mm bushings at both ends; the eye-to-clevis versions specify a 12mm ID × 21mm upper bushing. Confirm the complete custom mounting arrangement rather than assuming interchangeability.
The 335mm set explicitly lists washers among its included hardware. The separate OEM-type washer references 90521-292-000 and states two required per bike, without clearly giving supplied pack quantity. Compare what the installed mounting needs before adding another purchase.
