Dan,
The 65, 66 and 68 rear engine riders are off-topic for this section. Therefore, it won't be in the registry. Discussions about these rear engine riders should be made in the Late Model Section. If you need to know what year, try these:

Since they were made in the late 70s and early 80s, I linked to both decades.
