Yes, you're absolutely right, that's the way mine was done.  Will bolt right
up to 4kq exhuast.

No.

I haven't figured that one out yet either, but haven't tried too hard.

Yes, use the bracket w/o senders as a template and drill thru it.  Will be a
very clean job then.

Get a piece of 1" x 3/16" bar steel and a torch.  Bend 2 90's in it in a
vice, bevel the edges and seam weld it to the existing PS pump bracket.

I'd save the $$ and just go with a stock intercooler.  It'll do the job.

I'd worry about tires before brakes if it's gonna be a street car.
