Welcome to the Bolt, Toxictiki.

I took a look at the online Street Rod Catalog from this company and they had through frame fittings, and a variety of T's etc. for custom brake setups.

They also claim to manufacture all hard to find fittings for a variety of models to OEM specs so look the site over.
