I've had many requests from people to consider printing shirts, hats, window decals, and the like with the registry product logo so that folks who participate in the project can easily identify each other at events. I've done such projects before, and I have to admit that I really don't enjoy dealing with all of the product definition, order taking, money handling, and product delivery issues that go along with making such a project successful.
The Mustang 428 Cobra Jet Registry published our first registry book in April 2010. The book contains 275 pages of statistics, door tag decoding information, registered vehicle information (current as of February 2010), and part identification information. There are approximately 175 pages of color pictures! The book is published on 8.5" x 11" paper with a spiral binding for easy use as a reference.
We provide a self-service photo gallery from the registry forum that allows individuals to upload their own images and maintain their own text describing their cars. Note that the cars listed in the photo gallery are NOT the only cars registered - they are just the cars for which an owner decided to post pictures.
The Mustang 428 Cobra Jet Registry Forum is provided as a free service to anyone interested in the 428 Cobra Jet or the registry project. The forum is hosted on the registry web server to provide nice ad-free features at a reasonable cost. Registration is required to participate as a result of some shenanigans perpetrated by guest users; sorry about that. Terms of service and other legalities can be found when you register as a forum user.
