I don't believe any of the "rules" have changed involving registration requirements and driving restriction for antique, classic, custom or street rod.

what i know did change is.

1. you can use an old license plate to regisiter your antique or classic vehicle (they did run a check on the plate i got off ebay, i'm assuming to check that it's not currently in use by someone else)

2. they no longer are requiring pictures for antique or classic registration (the laws didn't change on whats required) so if you car/truck is questionable looking, you will be able to get it registered. this will leave it up to the police to decide if your registered correctly.

couple rules i remember.
you cant drive an antique at night, thats why it never needs a state inpection.

classic, antique and custom cannot be driven alot, restricted to shows and events etc.... says something about once a week. (classic and customs require yearly inspections)

street rod is the only way to register a car/truck that does't have any fenders or hood. they require yearly inspections, including emisions and you can drive them as much as you want.

i've build a couple "specialty construction" titled cars/trailers also,
if anyone has any simple questions, i've been through it a few times.
