I've been searching and ordering heater cores for my 92 RS and have been unable to find an original copper one. I've ordered from your usual parts stores to only find out that they only offer an aluminium one. I know the aluminium one will work but I would prefer to use the factory hold downs in the heater box to secure the core. So my question is has anyone found a supplier of a heater core that is a more direct fit? I have sourced a shop here locally that will re-core the one I have but at the price of $180 I thought I'd ask the experts here first. Thanks!

 

Thank the EPA and the dipshit who decided the lead used in a traditional heater core was killing tree frogs in Sumatra.

 

How true that is and that is the world we live in now

 

I have finally installed the new heater core and am having a hard time finding a diagram of the way the heater hoses run on a 305 TBI motor. I have found many for the TPI. Does anyone have a heater hose diagram for the 305 TBI set up?
