Cobrasnake,
As I have said it many times, I am just rendering an educated guess having gone through this and having watched friends do the same.

I would guess a bill of sale and a separate invoice from your installer for engine trannie and his labor should be all they need to issue you, your SB-100 number which is the prize you want to keep your eye on.
If you wait until the installation is complete and then get all the invoices I guarantee you it will be too late!

Yesterday I decided to book an appointment on line for January 2nd. There were NO appointments available that far out. I doubt it seriously others already booked those days to renew their driver's licenses.
Not surprisingly even though the January 2nd. is booked, there are plenty of appointments available in December!!

You can figure out what this means...

SO I went ahead and made an appointment some 75 miles away.

Why do I think all 500 numbers will be gone on January 2nd.?

AS for engine numbers and such, I doubt it dhoti DMV will ask for those. If anyone does it would be CHP and smog referee..
But again, there have been so many variations from one registration to another during 2003, please do not take my word for anything I have posted on the subject.
