Here is the spare tire J Hook hold down assembly from a 2007 P71
Ford Crown Victoria Police Interceptor. Should be the same for 2003 to
2011 Police Interceptor, Ford Crown Victoria, Mercury Grand Marquis
& Lincoln Town Cars, also 2003 to 2004 Mercury Marauder, May also work for 1998 to 2002 of the same models, you decide.
This J Hook is made, so the wing nut is removable from the shaft, makes it easier to install.
J
Hook measures 4 5/8'' overall and the mounting disc is 3 3/8" diameter
& the wing nut measures 3 5/16" across. Threads are good and measure
5/16" with the hook measuring 5/16".
Part number 5W7Z-1448-A, replaces 3W7Z-1448-AA.
