I do not recommend you tackle the PS lines until you have the K member and engine back in place. Line lengths really should be custom tailored once everything else is in place (engine, rack, all underhood items), as one small little change in routing can make for quite a difference in finished line lengths. There are so many different ways to route the lines, that it becomes much more a matter of personal tastes than anything else - hold off on this until one of your later steps.
