Edit Reason: aded depth of recess
)
Big 7 axle end. 5/8" king pin.
underside of kingpin eye showing recess that thrust washer partially fits into. Dia 1 1/6". Recess depth = 0.176 inches.
Big 7 Stub axle bottom thrust face showing about 1 1/4" of thrust face. Note there is no flange on the bottom king pin bush.
Big 7 stub axle underside of top king pin hole. note also about 1 1/4" dia. surface around king pin bush.
Hope this helps with visualisation of difference between 7 and big 7. (it takes the same hubs and 7" brakes)
