These trucks had 3.55 or 4.10 gears. An easy way to know what you have is jack up the rear end. Mark the inside of the rear tire at the ground and mark the driveshaft. Now turn the driveshaft and count how many turns it takes for the tire to make one complete turn. Really can't help with the clutch stuff... Sorry too..

You can tell the axle ratio by looking at the door sticker (presuming that the PO did not change axles or ratios). There is an "axle" category that will tell you in code. Somewhere on this site, somebody has posted all of the codes for the various years. Or you can jack up the rear end...
