[BR3W CITY]

^Basically what I had to end up doing. But I will offer a little advice from working mine out (and they aren't finished yet either). The firewall isn't 100% flat under where a full bracket bolts up, so 4-bolt square bases won't fit the best. If you use the two top bolt holes, you can make a t-bone shaped base that uses a 3rd stock (unthreaded) firewall hole.

The surface where you bolt the hinge isn't plumb either, its actually canted a very small amount. If you make it perfectly plump, the hinges will try to bow it slightly with their "knee" action.

And you will most likely want to box the open side. Mine is setup like that (just flat stock, not drilled/relieved) and the weight of the hood is far enough away from the firewall that the very end can experience some flex. Boxing that piece takes that problem away (and saves you from having to go to a thicker stock) as well as giving you a place to start a gas-assist or spring-assist since these relocations generally lose that feature.
