Engine Set Up?
Hi!
Drill a spinnerbackplate could ofcourse be done but better is to use a lathe or a reamer so the the hole is corectly centered..I asume you are going to use Tru Turn aluminum spinner?!...If it is a plastic spinner.... Forget it and use a
aluminum spinner nut instead. Much better than a cheap "wobbly" plastic spinner.
