CA Registration details with a SPF

[cobrasnake]

While I won't have my new SPF by January, I expect to pay for and receive my MSO (requested [and to be paid for] in order to register under SB 100 in 2004). I don't expect to install my drivetrain before going to the DMV or for that matter have serial numbers for the engine or tranny. Some questions for those of you with experience.

1. Besides the MSO and a fat wallet, what else do I specifically need to take to DMV in January (I have read many threads but want to be clear since I am quite dense)? I don't know what SPF will include with the MSO but the only other thing I currently have is the original sales order from Dynamic to show what I am paying for the roller.
2. DMV form 256 - Misc. Statement of Fact - since I won't have been to the CHP, do I provide the SPF chassis number as my VIN or will this eventually be filled in after going to the CHP? This would be true for all SPF's as no one at this stage has their actual VIN without going to the CHP.
3. What year and make do I put down on this form #256?
4. They ask if the vehicle was constructed BY ME or FOR ME BY: _____. Since this is a SPF roller, how is this one answered?
5. In this same paragraph they ask for BILLS OF SALE for the engine and tranny (I will have the info on the body/frame = MSO paperwork). Since these have not been purchased, do I just leave them blank? Do I then just estimate TOTAL VALUE OF VEHICLE at the end of this section based on the engine and tranny plus their installation cost plus the cost of the roller, predicated on the drivetrain I expect to install? Do I leave this blank?
6. DMV form 343 - Application for Title or Registration - same question regarding VIN as I asked in above item #2. They also ask for MAKE OF VEHICLE - is this the same answer as my #3?

Any thoughts on timing of insurance - since I will have paid for the roller even before I get it, one assumes that I should have my insurance commence when I write that check.

I ask for your guidance so that I don't waste time in line and I register it properly. Am I missing anything else. Thanks for your help. The excitement is building!
