Upper A arms for brake swap

First try at a post, so be gentle. Have seen all of the info. on using different spindles for an A body. I've got a '67 Barracuda that has the origional drums that I am presently trying to get up and running for the short term. My Question is that the conversion seems to be straight forward enough right up until the fact it appears that 73-76 A-body upper control arms are required. Obciously these aren't "Pick-a-Part" attainable like the rest of the stuff. What is everyone using?
Thanks, in advance,
Mac
