I think something lost-- My truck is pretty much original-- 10 lug rears , 4.47 center hole, 7.25 lugbolt circle-- front is a 5 lug with a clamp plate-- It is a 53.
Now, according to your chart in the tech tips, the later trucks (post 53) have stud-piloted wheels with a 7.25 lug circle ( same as mine) but a 5.25 center hole. My original question is can later model wheels with the correct lug circle and the 5.25 center be used on my truck with the correct stud-pilot lugnuts without any center hole spacer-- the lugs should center the wheel. Reason-- seems that the later wheel dimensions are more common i.e. the P30 19.5 wheels.
