1976 Argosy Radiator
Cost for 4-row core core was $436.oo CDN, labour was $220.00(@$88.00 per hour), total on the procedure was $1600.00 and I feel a little hosed by the situation, but I had to get it done.
Prices on parts are between 30 to 60% higher here so I think you can do better with some shopping for the core and at rusted mechanic.
I have not had a major repair since I purchased 5 years ago so I have no. Problems with the $$.
Btw: love to see some pics of your Argo
