Tony..your mailbox is full so I will answer your question here.
For lack of a press I used a C-clamp. Basically, I set up the clamp so that the screw side [with the pivoting base, which was a perfect fit in my case] was positioned over the large plug and the stationary base of the clamp was on the opposite side of the housing over the small plug. I also had a thin piece of oak between the clamp and the small plug side to protect the housing. By tightening down on the clamp I was able to push the large plug inward until it cleared the thickness of the AAR housing. Hope that is a bit clearer? Once the plug is inside the housing I had one other small problem. The bottom on the plug was concave and was hung up on the 10 mm nut..there still wasn't enough clearance for the plug to slip between the nut and the housing and fall free. I was forced to gently pry the plug over the nut to free it. Don't bugger the hole doing this. I then cleaned up the buggered spot on the bottom of the large plug with a file and slightly tapered it so that if I had to repeat the process the removal of the plug would be easier. Worse case scenerio would be to have a new plug machined. I guess if you had the skills to machine a new plug you could just drill out the old one rather then use my method. Again, you need to be careful because the plug needs to seal. If it doesn't, there will be an air leaks and that will effect the idle speed.
