Doing a body on fuel and brake line replacement on a 1980 olds cutlass supreme coupe 4.3L/260 not positive which trans. Was made in Quebec, Canada. There’s a couple bolts in super unreasonable places bonding the lines on, any idea how to get them off without taking the body off? Just trying to get the lines redone without taking the body off. Any ideas for material for replacement lines? Was thinking about bending it myself because it’s one solid steel line pre bent and there’s too many tight tuts and the main line runs through the frame. Also doing rocker replacements and a bit of frame work by some lines so they need to come off for safety.
