King Pin Bush sizes - Tony Press - 03-07-2020

Help- can one of our experts advise the correct outside diameter of the standard King Pin Bushes  BL 7 and BL 8 and the upper and lower bore sizes in the hub.

The size measured from old bushes-  

Lower flanged Bush BL 7  OD 16.2 mm (41/64" ?) 

Upper plain Bush BL 8   OD 17.40 mm (11/16" ?) 

From a couple of Club stock bushes 

Lower flanged bush 17.46 mm (which must be wrong ?) and 16.20 mm

Upper plain bush 17.44 mm

No comment- so I will take dimensions as below and suggest the stub housings be bored to a press fit 

Lower flanged Bush BL 7  OD 16.2 mm (41/64" ?) 

Upper plain Bush BL 8   OD 17.40 mm (11/16" ?)
