looking @kyb front strut mount bearing sm5064 anybody used these ? how is quality and fitment, installing on a early 1974 260z thanks kully

These appear to be the regular front strut steering bearing that gets sandwiched between the upper spring mount and the strut insulator. Can't imagine they would anything special or actually unique over the usual parts store parts. Who knows though.

54325-21000 Bearing strut mounting is the OEM number and description.

For reference and comparison to whatever pricing you're looking at, Rock auto shows them as :

BECK/ARNLEY Part # 1013848 {#5151008, 5432521000} Category: Strut Bearing $14.97

or MOOG Part # K9476 $16.89 (Prices are CAD, reduce by ~%10 for USD)

They show 543250B000, 5432521000, F3XY18H198A as alternate OEM part numbers

thanks for the reply and the part # from other manufactures kully
