Will Mapp gas work instead of Acetylene? I do have some of those yellow bottles I believe. Also, would you happen to know the Torque range for the Pit-man arm castellated nut

Yo, Dave....I don't quite feel yur pain...MY knees have hurt the past 30 + years, I don't have a lift, and I don't have a Cobra!
Seriously though, take a peek at the YouTube video in the link below. It shows a couple of guys using a rosebud acetylene tip to heat and bend a couple of old Ford spindle arms. These are essentially the same forged steel that's used in your Pitman arm. This video should give you an idea of how hot you need to get that arm, keeping in mind that your Pitman arm is actually a larger cross section, meaning you'll have to heat just a little longer for the greater mass of your arm. Also, you may notice that he's bending with a large adjustable wrench (more control) rather than whanging on it with a BFH. I spent a good bit of time yesterday looking for the torque on that old Ford nut. Couldn't find it! I did come across a similar-sized Mustang nut and they said 150 ft. lbs. PLUS! I'd snug it up to a similar tightness and continue turning the nut 'til you can insert a cotter pin. Click on the link below! DD
