Loaders/Model Numbers for 1982 Ford 7710?

[Spur]

What Loaders will fit a 1982 Ford 7710 with cab? Thanks!

My old Ford brochure shows two loaders are optional with 7710 tractors with cabs:
777B, but not on tractors with front-wheel assist
777F, but not on tractors with two-wheel drive

Thank you for your kindness!
