Denis; Unless your engine has been torn down, boiled out, and rebuilt, I would use single weight conventional motor oil. Using synthetic on a 50 year old engine is asking for trouble. For one thing synthetic is too thin for the tolerances that are likely to be encountered. For another it might dissolve some coagulated crud in the block and block an oil galley causing real problems. For the power steering use power steering fluid, its not hard enough to come by to justify substituting anything else. As for the transmission I believe that it originally took something called type "A" but someone else might have more information on a substitute.
