Need Service Manual for '74 Ford 2000

[BuickFarmer]

Anticipating tearing into the rear axle due to some hydraulic problems. Looking at eBay for manuals... are the IT manuals good or do I need an actual Ford manual? Any other better sources?

I have been less than impressed with IT manuals. I do not know if the Ford OEM ones are any better though.
