two header questions, and a word for Courtesy Nissan

[davidpertuz@mindspring.com]

I'm swapping headers this afternoon, taking out my old
Hotshot 3rd-gen and replacing it with a 4th-gen HS. I
picked up new hardware to use on one of my recent
courtesy parts orders. I know that I'll have to grind
down a few of the washers to fit around the welds, but
I also noticed that they seem to be directional - IOW,
there is a frontwards and a backwards way to put them on.
 Is this so, and if so, does the slightly concave-looking
side go facing out?

Also, one of the local (GA) guys is possibly interested
in my old header...it's a 3rd-gen Hotshot that I bought
and installed in August 1996. It has the crack on the 1-4
primary joint that they all have, which has some soot but
it is not big enough to make it loud or anything. One of
the flanges on the flex pipe is rusty and the flex pipe
might (?) have a small leak, though I can't tell by noise.
The finish (ceramic-coated) is in OK shape, pretty good I
suppose considering 7 years and 5 Michigan winters.

I don't have much idea what to ask for it (presuming he
wants it when I show it to him)...any suggestions on what
would be fair based on my non-pictorial description?

Lastly, I thought I'd throw in a good word for COurtesy's
service. I ordered some tune-up parts and a few other thing
the other week, incl. brake rotors to replace my worn-out
fronts. Thursday I had the car up in the air to do various
work on it, and when I got the old rotors off and took the
new ones out of the box, I found they had sent me the AD22VF
rotors instead of the smaller ones. Called them back, talked
to Butch, and he next-day-aired me the correct rotors, which
were at my door by 10AM! And UPS will come to pick up the
other ones, also no charge. True, it is better to always get
the right parts the first time, but this is the first mistake
they've made on any of the maybe 20ish orders I've placed
with them, and their repsonse was great, so I thought it
worth a word.

thanks,
david
