Tony,

    No personal attacks were intended in regards to the KB.  I truly 
appreciate the time and effort that went into its creation and it has 
helped me immensely.

    Oh yes, those inner nuts were a doozey.  One of those "Okay, I can 
sort of see them, now how the hell am I to get to them?" things.  It 
makes me wonder how the belt was changed originally.  There's no signs 
that the bumper had been removed previously.  Had I had a tool to remove 
the fan clutch, I probably would not have removed the front end either.

    I removed the two wires from the alternator and moved the entire 
cover to another bay.  I'm going to clean up those wires and clean out 
the alternator while its off.  Had an oil leak dripping onto it until 
recently.

    Any suggestions from the rest of y'all on how to get those lines 
back on?  I've heard you're not supposed to use the bolt to "pull them" 
onto the radiator but I see no other way.....

    Also, the harmonic balancer and the crank pulley came off at once 
and it appeared that they were one unit until reasoning dictated 
otherwise.  They're pretty stuck together.  I have a feeling I'm going 
to need to separate them in order to get the belt on and tensioned?  I 
didn't pay much attention at the time (and car's locked up in the shop) 
but is the crankshaft keyed to the pulley?  I would imagine it is so one 
could determine TDC.

    My chrome didn't seem to want to come off with just those two 
phillips removed and I didn't want to force it.  Do all those other nuts 
along the underside hold it on as well?  OR:  by off do you mean 
completely off the car, or just off the rest of the body? 

    Going back and looking at the KB again, I can see that the right cam 
shifted for you as well.  It's hard to make out details on my printed copy.

    Yes, the second bolt breaking was my own stupid fault.  Both times I 
was getting in a rush and not paying proper attention to how much torque 
I was applying.  I might consider going back to the oil pump and 
replacing the seal that's in there (I paid for it, why not?) that I 
forgot about and properly torquing those allen head bolts (I think 
they're over-torqued right now). 

    The water pump has been removed a couple times.  The Torx bolts are 
in there tight with a 1/4" ratchet (4.5" long) but I'm scared of that 
thing leaking once the sucker's back together.  Oy.

    I am not planning on dicking with the camshaft sprockets (i.e. 
loosening them for tensioning).  As long as I ensure a tight belt 
between the sprockets and on the non-tensioned side, is this going to 
cause any ill effects?

Another day in paradise,
Scott Simmons

P.S. ~ once again, folks, thanks for the help.
