let me know...I have been wondering the same thing...Isuzu was smart with one of their medium duty trucks and had access panels under the front hood...I have debated about cutting hole in the firewall...but for the most part in my experience removing the dash is the best way...in my s13 had to remove the impact bar as well...I wonder if you could break out the old plastic ones, thread the inlet/outlet and screw in new one? just clean it out real good...is also soft aluminum and may have plastic end tanks too...
