I redrew the diagram sticker under the hood of my 78 20R that is damaged and a little faded. I think I got everything except the upper left corner where the sticker was torn. Specifically connections around the EGR. The hoseswere all messed up from po. I rebuilt carb and need to get hoses in the right spots. Can't find any complete info out there. Can anybody help me out?I can send pic of the redrawn diagram, maybe someone else can complete it?
