Yachtsman, there are plugs in the rear wheel housing that lead right into the rocker! Also plugs in the lower front of the corners of the firewall! Unfortunately the mice nests and media came with the car!, it is all cleaned and blown out now! After half a day working on it! I took off the rear wheels allowing access to the rear holes! I utilized a ram rod that fit in the hole,vacuum cleaner in the kick panel vent and a long air blower! Worked It back and forth!, even put the air hose directly in the rockers! With Randy's twin compressors running full bore and 100 psi I got them cleaned out! What a fricken mess! The passenger side was easier as the factory a/c hole is there!
