The Stovebolt Site Forums The Parking Lot Big Bolts 56-59 GMC 370 factory power steering interchange?

Someone who has access to a Hollander Interchange manual would be able to read and find out, and I have a GMC illustrated parts book that is 4" thick and covers everything for 55-60 year models so I need to break that out and see what it shows for a 370. If the "big" trucks are different, then the GMC shop manuals will have to dedicate pages to explain the difference in rebuilding and servicing process too - I know several members have these books and can easily identify whether or not it is different....anyone got some manuals showing how to service a 370 series pwr steering sector?
