1983 Imperial sway bar Q

I'm getting ready to paint my 83 Imperial and also need to address the rusty rear sway bar mounts. Both are rusted pretty badly - one is broken off, the other is cracked and it won't be long. I need the part that bolts to the frame/unibody - they look similar to the ones on my brother's Gran Fury cop car...thus my question:

Are they the same?
Does anyone here know where I can get a clean (non-rusty) pair?

I figure the caps and bushings wouldn't be too hard to come by...or maybe I'm wrong?

Thanks,

~Q
