Randy,
I just completed this process a few weeks ago with a new brake pedal arm. I do not have a oxy-acetylene setup and MAPP wasnt hot enough. I went to Home Depot and got a Bernzomatic MAPP-Oxy kit. Worked perfectly. Took a couple tries but it got it just hot enough to bend. Buy a few extra oxygen tanks as they run out VERY quickly.
