[Desert.Chevy]

I have a 1958 Chevy c60 46,000miles 235ci sm420 with pto dump bed.
I have been replacing items and upgrading items of if I can.

Could this be used for an upgrade?

I’m looking for a gas tank oem of any kind or new, 9”-12” wide, 12”-16” tall, 3’-4’ long tank.
My idea is to put the gas tank along the frame but behind the toolboxes I’ll install.

What type of hose can be used for brakes and rearend?
Thanks y’all
