More than likely a "Special Order" piece I'm afraid...
Tousley Ford in MN has been a good mail order source, "Steve" is our best contact there.
Village Ford is a new sponsor here, "Andy" is their rep. and they have a section on this site.
I'd look close for other worn/damaged pieces, just 'cause of the likely wait for parts. SVT should have a metal frame for the shift mechanism, that's a good thing since a number of the plastic frames on other models have been found to break causing similar issues.
