Looked up the info, hoping for the best. None of the pictures of the pulley setups matched the situation I have. I believe all the engines had power steering so that didn't help much. I have an idler arm bracket and pulley already that does not appear to be a Mopar item as there are no part numbers on it. For now, I will modify the existing setup to be stronger and more factory looking. I think my son wants to put on a tubular k-frame with rack and pinion steering so a power steering pump is in the future and the situation will resolve itself. Thanks for the inputs!
