Computer geek here working on my daughter's car. Since the prev owner decided a large nail in the front/rear line and prop valve was an appropriate fix for a rusted front/rear line, I have a "new" proportioning valve and front/rear line.

Question is, what is the easiest way to route this (already shaped) steel line from Right Stuff Detailing? Top/down or Bottom up? It looks real tight with the headers. Any words of wisdom are welcome.

 

When I took mine out/in I loosened the transmission cross member and removed the driver side bolts and slipped the line in after guiding the front portion up to where it needed to be. I couldn't find an easier way with out bending it.
