I was taking my 79 new yorker for a drive when I hit a fairly large pothole. I heard a large thumping sound from the rear end and afterwards the car didn't ride right and became very bumpy. Upon further inspection I found a part of the leaf spring or hanger to be broken near the front mounting point of the leaf spring. Here is a picture. I am going to be replacing both leaf springs very soon, however I'm unsure if the split metal in the picture is the leaf spring itself, or the hanger. If it is the hanger, how would I go about replacing that.

It looks like where the leaf wraps around the front bushing has rotted out and fractured. The hanger itself looks OK.
I would avoid driving the car until the springs are replaced. This is a highly-stressed area as it is the point where the rear axle pushes the car forward and pulls it backward.

It seems to be the spring thats disintegrated, see the remains of a small weld on the bottom. ( the small bump under the bushing.)

I had a spring that broke right there. I think your only problem is the spring.

Looks like the eye is split off the leaf. Lucky. I've seen them broken and come up through the floor.

The rear hanger was more problematic than the front. The upper rear would wallow out the holes in the frame rail and pop up through the trunk. Also the bracket/clamp that holds all the leaves together can rust and snap. I’d give everything a good once over while replacing the springs.

A quick update - Turns out that the eye of the spring had broken around the bushing, and the bushing was the only thing holding the spring in place. It didn't seem like it was due to rust, as the metal was just rusted on the outside. I got new springs custom made by a leaf spring shop near me for only $170 a piece. They did a great job and the springs bolted right in. The original springs had an oblong front eye, which they weren't able to duplicate, anyone know why Chrysler did that? I was able to clean all the mounting hardware, like the front and rear hanger, and they were just surface rusted. Cleaned up the u bolt bracket and got all new bolts. Everything went together easy, only thing I had to do that took some time was I had to compress the spring a bit to get the rear hanger bolts to line up with the nuts in the subframe. I did that by just taking a jack and a plank of wood to lift the spring from the middle. Car rides great, although a little more stiff than before, and the ride height is maybe half an inch too high, but I don't mind. Thank you guys for your help!

The oblong bushings were to allow fore/aft compliance which softens the ride.
