before too long will be tackling my next project ......changing my rubber cab/radiator supports w/ new polyurethane mounts.is it recommended to detach the column to lift it up enuff to change the mounts?how about the brake lines into the bottom of the master cyl.?i believe the wires going through the firewall are long enuff to give slack to lift up the body..... any other pinch points that anyone thats done this happened to notice when you did this w/ a full body-on-frame truck?how 'bout the fuel line outta the tank?thanks to all who respond,later.
