John, Jeff, Owen, and whomever,
Steve Stegmann wrote a thread on the plugs used for closing off the 
emission tube hole, and he said that the end of the set screw that Owen 
calls a "rod", serves to eliminate the chirping that putting in regular 
set screws doesn't deal with. 
Even though he is from Missouri, he was "shown" by actual use that the 
Navistar ones are the ones to use. (g)
I used brass pipe plugs, but I think I may have had to rethread them. 
That was on my SSII and it was so noisy, that I couldn't hear the 
chirping anyway. If I do this again, I'm going to pay the extra for the 
Navistar non-chirping plugs.
