Power to Manual Brakes - D150

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.
How much per hour are you working for when you change an intake manifold?..
