Joe, here's the story. The logbook is so sacred that you don't get one issued to you until the inspectors arrive at your car/bike to inspect it. they carry them with their other inspecting stuff. They hand it to you and ask you for it. If it isn't completely and properly filled out they will flunk you for inspection and have you return to the end of the line, giving you time to fill it out. That makes sense, doesn't it?
More seriously, I think you get them from the registration trailer at SCTA and I don't know where from USFRA. I also don't k ow if they can be had by mail. You'll have to ask someone else about that.
The first page is stuff that will help identify your vehicle -- things like a serial number, if there is one, and manufacturer and date and other permanent data (that won't change as you modify and build on the original). You put your name and stuff like that there, too. I'd expect that stuff that you do to the car/bike in the original build for presentation for inspection should go on the front page, too.
You'll need a good photo or two or three of the race vehicle. That gets stapled to the inside front cover -- so the inspectors know that the vehicle they're seeing is the one whose book they're holding. And the book comes with your LSR chassis number sticker (usually in a small brown envelope attached to the cover (inside or out, front or back). The sticker has a number on it that coincides with the number on the book, and the sticker is to be placed on something really permanent of the bike or car - like the frame. The sticker must be visible to the inspectors so they'll know, again, that they're looking at the right book for that car or bike.
If you have any things that are different or unusual enough to have received comments from an official or if you've sent a query about something and received a response -- print it, including the name and the date of the official's signing, and keep that in the book, too.
If you want the officials to be sorta happy with you you can use the 3 holes in the binding and keep the book in a 3-ring binder. That also might make it easier to find the book when you're loading for an event. As so many of us say -- ask me how I know this is correct.
