I'm looking for 2 pieces for my magic aire heater in my 50 F-1. NOS or good used will do. Part number is 8c 18520, need 2 . These are the 2 elbows on to p of the heater core housing that the 2 flexible defrost tubes attach to. THey have a 45 degree bend to them. Any leads would be appreciated. Contact me at my email address, bjmccloskey@***.net . I can also send a pic from the parts catalog to show what they look like.
