~9:30 AM- ~7:30 PM most days COLORADO / ROCKY MOUNTAIN TIME ZONE

We DO NOT have your part
unless the following conditions are met:

a) You have searched our page(s) and have found the part you are
looking for SPECIFICALLY listed on one of our pages or you have
solid information that it's a 'bona fide' substitution for your part
(unless noted, we don't)
AND
b) The part that you have found is NOT marked
as SOLD or SOLD OUT.


If you do not see it listed after thoroughly searching the pertinent page
(likely the page you landed on originally),  
we do not have it,   
nor do we know when
it might come in,   
nor do we maintain "waiting lists" for parts,    
nor do we know who
might have it.

Sorry, but phone and email traffic for parts
we don't have listed or for parts that
are already marked "SOLD" has become too consuming of time resources.



 We try to keep these pages 99+% updated.
If you don't see the part you are looking for, simply check the web page
periodically as we never know what will show up each day. Thanks!!!!!


ALSO: When e-mailing be sure to include a relevant subject, ie: Brand / Model number / reason for inquiry
in the
'SUBJECT LINE'.
SUBJECT
lines left empty, or with 'single word' text like;
"Hello", "Hi", "parts", "stereo", "inquiry", "question", "selling" or similar or similar 'un-qualified' terms will
automatically be deleted by Anti-Virus / Spam settings or receive 'Low Priority'.
(Subject lines left empty show up as "No Subject" and are deleted automatically
by our anti-spam settings"
