1956 spring hanger bolts

[LDP 56]

Has anyone removed and reinstalled the rear spring shackle hangers? Are the hangers attached with carriage bolts instead of rivets? I'm assuming they would be reinstalled using grade 8 carriage bolts, and the holes in the hanger are square broached?

Why do you need to take them off? Besides the fact that the one shown in your photo has the shackle upside down, it can easily be flipped back.

Original from the factory had rivets holding the spring perch brackets to the frame.
The replacements are bolts. ..Grade 8? ..YYes, I'd be very concerned about low grade off-shore made carriage bolts from a generic hardware store.

Unless there’s an issue with heavy rust or damage they’re not usually removed for a body off resto. I’ve never seen a set removed.

The picture of the hanger in the first posting was from a different car. Ours is shown in the pictures below, that I took last night. Planning on removing the hangers and welding in new steel plate and reattach with carriage bolts. We're not doing a restoration now, just making the repair so we can drive it again.
