I can tell you that the bracket on the K-frame which the LCA bolt connects to will break first since my 1984 300D was cracked when I bought it. The owner said it had been stolen and crashed into a curb, which had torn the K-frame spot welds from the frame rails and shock towers. Either the shop missed the LCA bracket or it later cracked. Anyway, I repaired that bracket better than new, plus the side attachments when the shop's poor welds separated a few years later. In other words, the LCA bolt and eccentric washers is so much thicker than the sheet-metal brackets that even if made of cheap steel the bracket would break first, unless of course made of cast-iron or such, and seems you can never be sure if made in India.
