Welcome, Busta! We have two 2001 Phantoms and a full set of manuals for them...plus lots of experience with them. For example...I just changed out some suspension airbags in one today. Feel free to ping me with any questions.
They're a great platform for a build...great headroom, a pretty flat roof/ceiling, and lots of room below to add storage. And, they drive like a dream! My 13 year old has even driven one of them, on an abandoned road.
What engine and tranny does yours have?
