Engine oil cooler lines What to do

[GmtGmt]

my lines Did not Leak when i bought it home, i has been siting in a barn for the last 5 years, but they have been bent and have some kinks and have been welded before

i would like to change the lines and the oil cooler because its old and not looking to good any more

so i was thinking about cutting the pipes where the ends are with like 4 inches of pipe flare the end i cut like a brake line and replace the metal lines i cut out with hose insted and use some some good hose clamps and replace the oil cooler with this
