Ok, I searched and could not find, so...

I have a SM420 from a 52 long bed with a torque-tube drive line. I need to couple it to an open drive-shaft which will connect to a mid '70s 3/4 ton rear-end. I've seen pictures of an SM420 online with this desired setup. Can anyone share any knowledge of an aftermarket or later model rear transmission cover plate that will couple to an open drive-shaft u-joint yoke?

Thanks. This website rocks!
