I can get you half way there - Borgeson make a power steering pump bracket that incorporates the engine mount - their part # 802404 for $84.
Further Google searches show Autocity Classic has a similar bracket for $47 part # 5557PSM-FM. Southwest Performance Parts has one for $34 - can't find part # for that one.
I imagine it shouldn't be too hard to get an alternator mount to suit your 57.
