Be forewarned, 6G72 3.0 liter comes in both 12V and 24V
variants. They will not interchange heads blocks etc.
1994 I believe is the year they made the switch. So if
you are replacing the whole tamale it might not matter.
But those parts don't match up. I would pop a valve cover
to find out which 6G72 it was.
