I ordered a new heater core for my 1967 Camaro. When I opened the heater box, it was full of mouse. I cleaned and repaired the heater box and went to install the heater core and it didn't fit.

I went to return and or replace the heater core and too much time had passed. I tried to contact customer service to let them know the fitment for the part was off, but they don't have customer service.

I tried to do a warranty replacement, but answered the questions truthfully and they will not allow me to do a warranty replacement. I now have to throw a brand new heater core in the trash and go someplace else that will help me find the right heater core for my car. Such a waste.

I hope somebody reads this before purchasing a new heater core from Rockauto.
