Battery cable routing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looking for battery cable routing 66 C20. The ones on the truck were aftermarket and suspect.
Positive: I've identified the lead to horn relay and routing but main cable I'm finding 2 possibilities. Assembly manual suggests frame routing but not sure what year that is. I also see a reference to a clip on the oil pan elsewhere.
Ground: Assuming to block but not sure where, there are 2 holes on passenger front of cylinder head. On cable there is short (12-15") #10 wire with eyelet.
Here is picture
