Dale,
Your parts truck does not have the same wheels that Jeff started this thread about.
You have the normal Chevy 5/10 lug wheels as expected on 1.5 and larger trucks.
Jeff has "Motor Wheels" which are 5 lug front and rear and use different hubs.
Both of the above wheels are hub piloted.
They are not stud piloted "Budd" wheels.
Check this Tech Tip out for an explanation on hub and stud piloted wheels
