Dennis,
If you are a AAA member I would suggest talking to them first. The DMV is really clueless and they were very confused by my pan based IM. I think that you need all your build data documents, fill out a specialty construction form (PDF on the DMV website) and most important is your engine build year because this is what you have to smog, btw what engine do you have?
The DMV website is not bad and they have the forms in PDF and you can even fill them out and print them. They also have checklists with what you need. Here is a short list
DMV reg form
Title
bill of sale
Spec Const form
all build docs you can lay your hands on (for backup if asked)
a lot of time to wait in line (or go to AAA wish I was a member for this service alone)
Checkbook or cash (my fee was $1100.00 for a sale price of under 15,000.)
If you decide to do it yourself start by driving around to the back of the DMV office where the license test are given, a DMV guy or gal comes out and checks the numbers on the chassis VIN or IM numbers in your case. they fill out the 2nd page of the PDF reg form. be sure they fill in the right numbers, they will most likely be confused.
Then you grab your paperwork, patience, checkbook and smile (SEG) check in, take a number and wait. Not so bad especially if your wife does it like my gal did (she sure surprised me, and was somewhat of a nervous wreck by the time it was over) I had to remind her to calm down when she called me while she was at the counter explaining what a replica was to the confused counterperson who didn't have a clue. But the DMV people are OK and just trying to get through the day, remeber to not lose your cool and checkbook and you will be legal soon, or at least temp legal.
I want to hear your DMV story and good luck tomorrow.
Cheers
Dave
