Re the clutch line - that picture you have looks a little wrong, as you say it's been hand formed.
Mine's the original, it's basically a straight line, no curvature except for bends, and it doesn't make contact with the bulkhead at all*.
From the master cylinder it forms a P shape as it curves away and down under, then has a couple of 45 deg bends to align it for the direct run down to the bracket where the flexi line is, taking the shortest distance possible.
*That keeps it clear of the bulkhead and away from the starter cables, brake lines, wiring loom etc.
