help with purchase

[hertzad]

New to the site and to the classic car world so am looking for advice on a couple of things.
1. I'm in Pa. and plan to purchase a 66 mustang from my Uncle in Ca. He's the original owner and we share a last name, so I'm wondering if we can transfer the title without me counting as a second owner.
2. What's the process for buying the car in Ca if I'm going to register it in Pa? Our plan is to drive the car back across country, so it will need tags of some sort.

Thanks
