Power to Manual Brakes - D150

If I didn't have the piece of metal which I'm pretty sure I have I would go to the steelyard to their cutoff extra little piece bin and buy a piece of metal. Put it up on the firewall when it's empty and go from the inside and scribe the holes.. drill them out and be done...
My problem is I like fabrication and I don't have a lot of money...
First of all, I want aluminum. 2nd of all, if it's going to cost me money to buy the hardware, and hour of chasing around to find the material (where I live, could be 2 hours round trip), and another 2 hours to make it, plus my gas, you see where I'm going?? 3 - 5 hours total ... I don't like working for 6 bucks an hour by the time I pay for material and gas. Some times if you can buy for under 50 bucks and have it show up all ready to bolt and go, I'm way ahead.
