Hi everybody! My name is Ron. I have a 1983 CJ 7 that I have had for some time. It is needing a lot of work. Hope to get some help here.My main problem is a water leak that is coming from the fresh air intake. The plenum box just under the grill in front of the wind shield has a drain that has broke off and is allowing water to leak into the cab. Has caused floor board to rust bad. My plan is to remove the rusted part and tig in some new metal after the leak is repaired.My problem is I can't find the fresh air intake duct anywhere. Mopar parts says they are all gone. Any suggestions would be appreciated.Thanks,Ron
