Mate, you are doing an amazing job there!
I have the exact same brake set up as you... and I'm loving what all your wiring looks like. Mine unfortunately has some white over spray on it from when it was painted a few years ago. I'd love to redo mine like yours, but the engine bay is no where near as clean. What do your brake lines look like. I replaced all mine with SS, and I found that the replacement front-to-back line for the rear brakes was a little too long. But it worked out for the dual master anyway. I'll take some pics as post. I'd like to see yours! BTW... those spray nozzles you sent me are in and really look great... and a great story about them to boot. LOL!
That black plastic rectangular firewall blocking plate.. where did you get that? I'd like to replace mine.
