The shim here is the MOPAR part, numbered 68146522aa.
[2.19 mm].
The number stamped on the old part is the only reliable identifier, since two parts can look identical and differ by a millimetre or by rotation direction.
Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone.
