I saw not too long ago a walk through for setting the pinion depthand all of the necessary steps rebuild the rear end. Also I need to image of the Drum Brake components. I cannot find these anywhere...

Setting the pinion depth is the biggest pain. I dont know where teh diagram is but I can explain it.

First off if you have an old large pinion bearing take a die grinder and inlarge the hole so it slips on and off the pinion. This is called a dummy bearing. Once you have done that take the old shim off the original pinion and measure it then select a new shim of the same thickness. Install the shim and dummy bearing onto the pinion. If you have not done so already installe the small pinion bearing and the pinion seal. Slip the old crush collar onto the pinion and install the pinion assembly into the axle housing. Install the pinion flange and the old pinion nut and snug them up. Next install the carrier with enough shims to hold it in place (doesnt matter is backlash is correct or if there is side to side movement). Now take the marking compound and mark about 4 teeth of the ring gear and run it down onto the pinion a few times. When you finished that rotate the ring gear up so you see the compound. What you are looking for is how deep the gears mesh (from the face to flank or the top of the tooth to the bottom where it meets the ring). You want the patter to go most of the way down into the gear (a little past center is suffiencient). Too far down and the teeth on the pinion will break off. Too face up and the ring gear teeth will break. If you need to adjust the depth do so by changing the shims. A thicker shim will make the gear mesh farther down. A thinning shim will make it mesh higher up.

Let me know if you need anything else.
