Booster Brace and Rear Brake line ??

[GOPAPA]

I would like to know just exactly where the brace fastens on both ends that braces the power brake booster... I took a stab at it and you can see in my photo how I (shown with a white chalk mark on it )hooked it up and it seems strong ,,but still would like some opinions ..

And also I have a question about the rear brake line and the bent out flap on a cross member. If I run the line through the hole in the flap then the line will cross into the side where my Blazer tank is and be much harder to get to, for repairs ,if needed.. the line is not correct in the picture as you can see but I am re-doing the whole line down the frame anyway . I thought again if any one had opinions or Pictures of what you have done ,,that would be appreciated.. thx for reading ,,papa
