Default Wrong new rear brake caliper?

my jobber sold me a left rear brake caliper but I am really struggling to get it mounted.. it is way off center. the caliper metal is actually grinding on the rotor ( new also ). yuk...
I was looking at the parts houses and there seems to be a part number difference between the left rear and the right rear.. they seem to eyeball the same but are they? is that my problem? I already gave them the old core too. more yuk..

they gave me the correct part as it says on the receipt but perhaps was the wrong caliper boxed up and placed in the box?

the caliper is cast delco moraine 6473807. mine is a '70.

any theories?

Is the bleeder pointing up or down ?

Should be pointing down...left and right ARE different.

bleeder nipples are correct, pointing up in the front of the rear caliper, both inner and outer.. with bleeder 'plugs' installed at the back end of the caliper

You might have a front rotor on the rear. Does it have the holes to adjust the parking brake?

no parking brake holes, i figured it was just a characteristic of china that the adjusting holes were not there.. i usually just adjust the parking brake out anyway to a close contact anyway and back them out a notch before putting on the rotor..

it does have the offset and the area inside for the parking brake shoes..

Since there's no PB adjusting hole, you most likely have a front rotor. They look the same, but the rears have the hole on them.

Yes, they used the same blanks just machined them a little differently. It is very hard to tell the difference in them by casually looking.
