need help identifying a set of ladder bars

[68 Malibu]

I have a set of ladder bars that were removed from a '69 442 a few years ago. They bolt in, and replace the lower control arms. I contacted Lakewood to see about replacement bushings for the front, as the back is simply a bolt that attaches to the rearend. After describing the ladder bars, I was informed that Lakewood never made any ladder bars that "replaced" the lower control arms. Only ones that were used in conjunction with the lower control arms. They appear to have been painted yellow originally, although now are somewhat rusty.
Can anyone help identify these ?

Thank you for your time,
Kent
