Burb buckets in pickup, where to buy stainless brake lines and steering box

[hrc200x]

I'm wanting to switch my '83 pickup to the light grey interior from a burb, the hardest part might be the seats, going from a bench to burb buckets. It appears that one of the bolt holes from the burb seat lines up with a hole in the floor in the cab, it'd be the front left one if your sitting in the seat, the front right one appears like a bracket would need to be removed from the floor of the burb and welded in the pickup cab. The two rear of the burb bend downward, where the pickup bend up upward. Could the brackets from the bench seat be removed via the mounting bolts and be mounted to the burb seats without too much trouble? Or would just heating up the burb brackets and bending them to fit be the way to go?

Seems like steering boxes on these old pickups are common to have about a 1/4 turn of steering wheel play. Where have you guys bought new boxes? How much were they?

Also I have a 6 inch suspension lift, I'm having a hard time locating extended stainless steel braided lines. Have found them for 4 inch, but not sure they'd be long enough for 6 inch lift. Where to find the cheapest ones available?

Thanks.
