Parts Interchange

Yup. Truck pan is different. So is dipstick and tube, goes with pan. Actually goes into the pan itself instead of into the block.
As far as that wiring you're talking about which end of the white connector is bad? Battery end or harness side?
I've bought factory style battery cables with that connector included. I've seen them on eBay too.
I have a few of them brand new yet. There's a place in Ohio I go once a year, (damn I can't think of the name of the place, it's "something surplus" that has a bunch. Even though it's a POS cable they're black though. They never had a neg cable that I know of with those connectors.
Problem is that if you use a universal cable I think the harness end went into that connector went into a 4 way fusible link connector.
