A 13 year olds rusty fleetside 4x4 65 chevrolet frame help

[preston65]

My dad spent 19 years trying get this 65 Chevy. He finally got it about two and a half years ago. I always had a liking for the truck. To my surprise he gave me the keys, title and a brand new fender on my 13th birthday. I'm looking to get it driveable by the time I turn 16. the frame is one of the first things I want and need to replace. we want a later model frame so that we'll have power steering and so we can keep the newer brakes. It is currently sitting on a 63 burb frame. It is 4-wheel drive and I would like to hear from you all on what frame setup will work best for my truck thank you.
