are you back in lowell now?
if so there are three junk yards fairly close.
there is lowell used auto parts on tanner st.
tanner street is right off of the lowell connector, exit 4.
then there is Jacks.
that is off of 495 exit 37. heading towards billerica.
then off of rt 3 exit 27 (i think) is hollands.
good luck finding your parts!
