I have had my 69 Barracuda's PS box in and out several times. As I remember, it is held in with three bolts. No mystery, you just take them out. There are no nuts on the other side of the bolts, they just come out. The bolt heads on mine were rather strange (original??). They were 12 point, and a 1/2" 12 point socket fit fine. I also remember they are a bit tricky to get to, because I have headers. Nothing an extension and a U-joint can't handle. Make sure the Pitman Arm and steering shaft linkage are disconnected first. Then keep in mind the PS box is HEAVY, so be prepared for the weight. If you have headers, getting the three bolts out is not the problem. Getting the box past the headers is the fun part. I have to take all the bolts out of the driver's sider header, then hold the steering box with one hand, hold the header with the other, and wiggle everything just right until it slips out. For your sake, I hope you don't have headers.
