Quick minor questions

[Grappler]

So just getting things finished up so I can get my 7 out of the garage and driving before summer is over.

Q.1

According to that other forum bolts on the Powersteering rack for looping the lines are 2 m12x1.25 and 1 M16x1.50 both about 10mm long. Where can I find some? I have checked atleast 4 different hardware stores and none have them.

Q.2
I am using an Rtek ecu for my 6 port turbo setup and I have retarded the timing using arghx's timing maps should I enrich the map a couple percent or should it be fine till I get to the dyno. I plan on staying off boost just to be safe.

Q.3
Does anyone know which wire is a switched 12v line is on the stereo system? I was planning on tapping my gauges into there using the light on the cig lighter as a constant 12v and such.

Heres whats in my car
