How do I switch an 8.25 Small Bolt to a Big Bolt pattern?

Also the 4" and the 4-1/2" is the technical measurement from where to where on the wheel?

Those Billet Adapters Look Good But The Problem Is The Ones I Got Now Are Only Like A Half Inch Thick And The Only Billet Ones I Can Find Are 1 Inch or Bigger.

The One Inch will Put My Tires To Far Out, I Think Im Gonna Run The Adapters I Got And Just Check Them Periodically.

those adapters you have are 1" thick.
