1st Time for a JAG

Working with my 1st 5R55N Jaguar with a gentleman from Minnesota.  JAG does not have any cross reference information available for the servo part numbers.  It is a 2002 and the part numbers are the same as a Lincoln LS.  The OD parts are the same as the 5R55W explorer parts but the IM is much smaller.  The owner ended up sending me his original and I machined it for him.  For the 2002 LS and the JAG, There are two sizes of IM servos that I got the part numbers for from Ford.

The descriptions of the two parts are as follows:
Piston, Intermediate Servo (Bonded)(3.505"OD Large Lip) (2.520"OD Small Lip)
Piston, Intermediate Servo (Bonded) (3.505"OD) (2.820"OD Small Lip)

Given this experience I would be able to track down fairly easy part numbers for Lincoln's and Jaguar's.
