    Probably. I'm in Ontario Canada and bought it in Canadian Tire and I know the States has more products than us.

    Don’t know why but both my hoses are 5/8. After I got the 3/4 to 5/8 bypass. Ugh!

    Someone was too lazy to get both correct hoses in your case.

Working under dash worse than under hood. But it’s done. Still need to remove that black block off plate. Looks like they trimmed carpet around damn evaporator. Going on epay unless someone here steps up and wants it.

    Looks like my radio doesn’t work because it’s unplugged. Now I need heater system to replace .

    First of all do original battery cables have the extension coming off of them? The positive goes to a junction block tucked up under the radiator support on the passenger side. But my negative also has one of the extensions and it was not attached to anything though I see a place for it on the inner fender well. Are they like that originally?

    Next question has to do with the wire harness running on the driver side inner fender well. It would appear that my harness should be sitting up higher on the inner fender well though there doesn’t seem to be any other place to attach a fastener. Am I missing something?

    1 strap on the drivers side. I would use a hair dryer and warm up the wire harness then form it.

    The AIM shows two straps

    My inner fender has holes for two straps. The one in the back is pretty far back. Not quite like what is shown in the picture.

    Both cables have a small lead wire on them, and the negative does attach to the inner fender where you see the hole in your first photo, and uses a star washer. Photos of original factory installed cables:

    My '70 Norwood Z/28 has two plastic straps holding the wires on top of the inner wheel well in the molded channel where they should naturally lay....sorry I don't have any pics. Like Dave said, the rear strap is further toward the firewall than the AIM appears to show. It's almost directly under the hood hinge, about mid-way between the two hood hinge attaching bolts. Your wheel well should have two small holes there..

    And there's the other strap. I thought you were wondering in the area where yours was sloped down.
