89T is the body style for the Falcon Super Custom Club Wagon.
NOTE: The rear bumper shown is for 1961-1964 models. The 1965-1967 models had a straight bumper.
NOTE for further research: What is the difference between the 89L and the 89T? The 89T may not have had the side trim, so this might be the wrong picture.
Thanks for the positive comments that have been left on this site. It is still a work in progress.
