Brake Master Cylinder

[SAJanesick - Bellsouth]

Scott,

The bottom link from AutohausAZ lists an ATE OEM part for the TQ20V. That is 
the best example I can provide for you although I also found it referenced 
in the ATE web catalog as:03.2125-3610.3 010214, found on this link: 
http://outcat-cs.tecdoc.net/ows/en/CB4BA8AD2CDA5863BDF349DD8C22D2EE.ows_cs1.srv;jsessionid=CB4BA8AD2CDA5863BDF349DD8C22D2EE.ows_cs1?view=VIndexFramesetJsp

After reading your information about rebuilder reluctance on aluminum parts, 
I looked back at the RockAuto CENTRIC part that I purchased and it is NOT 
listed as a rebuilt unit.  I mistook it for a Cardone rebuilt unit below it. 
Make sense as there also was no core charge on it.

The question still remains as to whether or not I could simply plug the 
unneeded holes and carry on from there.

            - Steve
