I'm replacing my heater core and purchased the heater box/core gasket set from one of our restoration companies. I didnt receive any instructions for the 10 gaskets that come in the bag. I called the parts company and was told that they dont have a diagram nor did he have any ideas at all about installation, where, or if I needed all 10 gaskets. (Oh non AC) Now yes a couple maybe a few gaskets are just plain as day where they go. Does anybody happen to have a diagram/instructions for the gasket set? Or any feedback on your installation of the gaskets whether you used all 10 or less would be appreciated. Thanks Johnny.
