Slow and easy.... I'd the undo the filler neck, unbolt the brackets from the frame, and drop it down slowly with a floor jack. Watch the hoses, sometimes they don't have much slack in 'em.
Other than that, not much to worry about.
Took a friend of mine and his son out for a ride last weekend. Fun as hell seeing the grins on their faces during the ride.
Although, romping on it as hard as I was, I think that third gear is slipping under extreme load/power. Should probably start planning for a rebuild here eventually.
Bed sides definitely need to be spread apart to get the rear panel out. To get them spread apart far enough though would probably require most of the bolts to be removed from the sides.
2x6s would probably work... I had used a 2x10 or 2x12 if I remember correctly to lift a BBC off a trailer once many moons ago using a couple of chains and a come-along.
Entirely possible for it to die at any point/time... The modules are heat sensitive and if it overheats then it's just a matter of time before it just conks out.
If you replace it, then make sure you clean off the mounting pad real good and put some new heat transfer paste back on it before...
Finally got around to diagnosing an issue the ol' girl had with surging, backfiring, and generally just not running right.
Turns out she just needed a really good tune up for the most part. :)
I'm with Georgeb on this... I'm still learning about and tuning my Quadrajet, but it's definitely a good carb. If you think you can do the work yourself then I'd buy something like "How to Rebuild and Modify Rochester Quadrajet Carburetors" by Cliff Ruggles. That book has a lot to offer...
I have a feeling there's a longer cable that is used for the 4x4s. LMC Truck shows different numbers depending on several factors including year, transmission, and whether or not you have cruise control.
Aw hell... I wasn't paying attention to the fact you have a 4x4. For the 4x4s the speedo gears are in the transfer case itself. The transmission should've had a blank plug installed instead of the rtv'd gear housing.
I'd look on the tail housing of the transfer case for a similar gear...
I went to compare your pictures to the ones I took while doing my speedo fix and from what I can tell, you're missing the drive gear. That small one is for the governor.
Here's the post where I have the pictures from mine.

I like using this site... you can play around with the drive gear numbers to figure out the different combinations that will work for your set up. :)

You're correct that that gear housing is for gears with tooth counts from 36-39. There's another one for 40+.
You really need to determine the gear ratio in the rear end before you can figure out which driven gear you need. There are a few different ways to calculate it.
Here's a...
Can you get pictures?
I've always had luck finding speedo gears on ebay. There are also sites like http://transmissioncenter.net/ that offer all sorts of part including those gears.
Those have some heavy duty inserts on them... I would think that you might be alright, but you can replace the whole guide if it makes you feel better. I had to replace one of the guides on mine when I busted it while installing a liner in it.
It's for a vacuum booster... Sets the actuator rod on the booster at bit of an angle and the pin on the pedal is smaller than the one on the hydro pedal.
It's works in its current config, but I foresee it not being healthy on the booster in the long run.
