Just bought my '66 Dart and have some questions!

1. The pitman arm bolts to the output shaft on the steering box and connects to the steering linkage.

2. Dunno. Never had any problems with one. I would say anything more than 350 HP will need a performance build.

3. More than likely a wiper arm pivot seal is bad. Schumacher Creative Services (www.engine-swaps.com) got their start making kits to fix this problem. Pretty common problem even on new cars. My dad drilled 3/8" holes in the floorboard of our '67 Valiant to give the water that leaked in a way out. Wouldn't hurt to clean out the cowl drains either. Keeps the bottom of the fenders from rusting out.

4. You're welcome. That's what we're here for.
