Thanks Fred.. and everyone who responded.
 
Sorry I was less than clear in my original post.. Thats what I get for 
posting while tired. I was indeed referring to the firewall mounting 
hardware with regards to the CCI mount.

I am now beginning to learn "all about AN and MS hardware" from the lady 
who owns the aircraft parts store. She visibly winced a few times when I 
described that I was helping build a (WINCE) homebuilt and we were 
putting an auto engine (WINCE) from Mazda (WINCE) on it..
 
All's well that ends well, though. she took some time to explain the AN 
nomenclature regarding the bolt specs so now I know what I am looking 
at/for. She also happens to have a BIG torque wrench thats good for 600 
ft lbs that she will let me borrow to ensure that the "big nut" is 
torqued properly.. She winced a few more times when I described how I 
was unable to find a large enough torque wrench at reasonable cost, nor 
a torque multiplier, so I described the 5 ft pipe on the end of the 2 ft 
breaker bar that I applied an approx 60-70 lbs to on the end (after 
practicing some 50-60 lbs pushes..).
 
Seriously she's a nice lady, been in the aviation parts/maintenance 
business for 40 years and she just wants to ensure the job is done 
right, and safely.
 
Anyhooo... thats all for now,
Dave
