Rare '72 Blazer?

[zgraham80]

I have a '72 Blazer that has a lot of options. I am about to start restoring it and have talked to quite a few people in my area. This is the most options they have seen on one. I am just wondering if it is rare or not. This isn't a Blazer rich environment, so it might be very common. The less common options are air, tach, and 4 speed. It is also has the CST option. They are all factory according to the build sheet in the glovebox. Thanks for any help in advance.
