Got the new Heater core for the Chieftain front dash today.
Pretty much the same measurements as what I took out, except it costs 103.00 with shipping, instead of 275.00 plus shipping.
103 is fair enough to me, as it is the size of about 3 heater core
1/4 inch difference in length. different inlets, and outlets, not a big deal.
Came from a company called Mill Supply, ordered from StepVan parts site.
This weeks project will be putting it all back together. in a new core box, I am fabricating to make future replacement, and maintenance easier for the core, and AC coil. will also be easier to clean the coils in the future.
