 BEFORE
CALLING
(719) 964-7205 
OR EMAILING
parts@oaktreevintage.com .

If you DID NOT see your Unit or Part
"
SPECIFICALLY"
listed, or the part you are seeking was already marked
"
SOLD or SOLD OUT"
then please
DO NOT CALL or EMAIL for it.
If you do not see it listed,   we do not have it,    nor do we know when it will come in,    nor do we have a "waiting list" for it,     nor do we know who would have it.
Sorry, but phone traffic for parts we don't have listed or for parts that are already marked "SOLD" is too consuming of time resources.

      If you DO see your part listed, and it appears to be available or you know for a fact that it is a VERIFIED-GOOD substitution from a unit or part that we do show, then by all means, give us a call to verify availability and to place the order.
 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!!!!!
