Sorry, I guess the first post with the above picture didn't go through. (picture was too large) Anyhow, I just found the Firewall Date Code last night(H42R). It is under the Heater Motor Box, mine was partially covered by the caulk. The other # is your partial VIN., (should match the 2 nd. half of the VIN. # on your title. Good Luck!
