Sorry thats D.O.S. 723K San Jose (Special Order Unit 3K)

Hello! Shawn

The data of your car is for a fastback, not a Mach1.

63B is deluxe interior fastback, and the BG trim is not available for a Mach1.

Make sur your serial number is a real 05 code ?

Let me know

Ray

Sent in for Martie deluxe report should have it in a couple of days.Payed the three dollars extra to have it e-mail in advance but some how it never made it.When I call the lady she said check my spam mail still not there.Called her back requesting some kind of confermation but no luck she said the guy went home for the day and she didn't have access to that info.When the mail man shows with it I'll let you now Ray. Thanks for the info.
Shawn.

This DSO makes more sence
