viewtopic.php?f=8&t=29834Your truck is a series 8, a series 8, 9 or 10 manual will serve your purposes, the 2wd trannies are all the same. The differences in the trucks are the sheet metal and the 4wd powertrain from '79-on.
A series 7 manual would also apply as long as '77s have the cable clutch, I'm not sure which year they switched from hydraulic to cable.

Since this is your first LUV clutch replacement do the minimum required, save the extras for a later time. I agree with replacing the pilot bearing but not the main seal unless it's actually leaking. The 5-spd would require at least some driveshaft mods that sticking with the 4spd won't.
You won't know the condition of your flywheel until you get the clutch plate unbolted, but if it's just slick & not scored I would be tempted to try roughing the surface with sandpaper rather than removing for resurfacing, again keeping it as simple as possible. If it definitely needs resurfaced then you might consider a new series 10 4wd flywheel instead along with the matching bigger clutch; the additional cost isn't that great & the labor's the same, just using different parts.
