In addition to the four bolts holding the motor on to the firewall, the wiper linkage appears to be bolted on from behind. Do I need to remove the glove box and a bunch of other stuff to get to it? Any clues greatly appreciated !!!

No experience in 100 series .. but in 60 / 80 series not .. just bolts holding the wiper motor and sure bolts that holds both pivots bases in place .. so in order to remove all linkage those bolts need to come off too ..

I'm going to start sharing tasteless jokes and PM'ing folks on this. Seriously, it's one of those things you look at and go WTF??? but it's probably not that hard. If I know how to get to the nut. What can I do for you all?

I don't think this is the case. Here's the unit in question:
The four bolts visible come out easily, the unit is loose and still attached to the linkage behind the firewall. I've pulled as hard as I dare. Besides, if the replacement motor:
is any indication, the motor is indeed held on by a nut behind the splines. Enough force is likely to result in the destructive removal of both motor and linkage with significant damge to both as well as the firewall.
I've removed the glove box stuff revealing the heater core, filter box and a bunch of other stuff. I'm hesitant to mess with the airbag, but the motor seems to be mounted just in front of it.
PLEASE ... is it really this complex to get to the this one nut? Someone must know.
Thanks again in advance ... Uglyhat Edit: sorry 'bout the photos being in the wrong places , first time.

I could be totally wrong about this, as it has been a while ago and I am going from "memory", but anyway....
I did this job on my 60-series, maybe ten years ago. I want to say that I removed the wiper arms and the nuts holding those fittings to the bodywork of the truck and then just pulled the whole regulator mechanism out from behind the firewall through the hole behind the wiper motor after the motor was removed. In that case, I was replacing the regulator because the plastic bushings had broken.
Once your motor is out, can you not see the fittings for the regulator that drives the wipers? It might be you can flip the wipers up and off the glass so they don't create drag and then pull the linkage toward you and out the hole enough to get it to engage with the back of the wiper motor and put the nut back on it.
Search the 60 and 80 series forums for possible pictures / procedures.
Sorry if I am misinforming you, and I admit it was a little odd the first time I looked at it, but it wasn't that complicated once I was able to study it for a while. But hey, that was ten years ago !
Good luck.

Parts diagram doesn't call out a nut on the backside.

FSM diagram does it. Those splines have been engaged for a long time, so there is a good chance that the motor may be a bit unwilling to release. It might take some wiggling to get them released, rather than a brute force pull. The fact that the replacement motor has a threaded shaft may be misleading - its probably used on several models.

I know what the FSM says; at best it's incomplete and misleading, at worst it's just plain wrong. I've pulled on the motor as hard as I can. In frustration I finally took a crowbar to the unit, adopting the old "if it breaks it needed fixing anyway". This resulted in some progress and minor damage to the firewall (red oval in picture).
In the process of trying to pry the motor away from whatever it was attached to, the unit popped out of the service port revealing a previously unmentioned-by-the -FSM lever arm secured to the motor with a nut on the threads visible in the picture of the replacement (black oval in picture). I believe the key is to simply work this around until it comes out of the service port, providing easy access to the nut where after removal it pops off the lever arm with a little encouragement.
NOTE: Do NOT simply pull on the unit, it is held on the threaded spline by a 12 mm nut and must be coaxed and coerced out of the service port whence completing the process is straightforward. The lever arm (wiper link) is hardly shown in the FSM (page BO-32), the nut needing removal is not mentioned (unlike all the other bolts in the assembly) and indeed the instructions do say simply "remove the wiper motor".
A quick whack with a hammer fixed the bent firewall, and the replacement motor bolted on without a hitch.
I hope my little ordeal here helps someone else avoid similar frustration in the future; thanks to all who replied.

Nice get! And I for one was wrong. Nothing quite like doing it to settle the issue, and we're all the wiser for your posts and pics. Thanx.
I could be wrong but - Every other wiper motor I have changed pops off the ball mount, you don't undo the ball mount arm from the motor. I expect the LC is the same. If it doesn't pull off you need to put a lever or screwdriver between it and the wiper arm as pictured in the FSM.
(b) Disconnect the wiper motor from the wiper link, then remove
the wiper motor.
I had to show the mechanic at Toyota in Conneticut how to do this on my Corolla in 1994.

I'm in the middle of a replacement. My new motor has the arm and ball joint. I think I can pry off the linkage from the joint on the old motor, but I'm not sure I can snap the linkage back on to the new motor assembly since the linkage doesn't seem to want to come out of the hole in the firewall.
Any ideas?

So, I thought I’d be a smart guy and leave the bracket attached to the ball joint and just bolt the old bracket onto the shaft of the new motor. As I was bolting everything backup I realized the issue I was going to have. By randomly attaching the bracket to the motor, I was no longer at the default return position. So my wipers were stopping mid windshield. It took a couple hours of trial and error rotating in the spline, tightening things up, trying again to get to bottom.
Long story short, I’d recommend attaching at the ballpoint.

I’m in the midst of this repair now. I can’t get the ball joint back together with the motor intact. Every time I push the motor in, the linkage scoots back and I can’t get it to connect. Any tips?
There should be a metal tab near the ball that you hook on the edge of the hole to keep the linkage from pushing in. Hook the tab, push the ball together, then unhook the tab and mount the motor.

Unfortunately, my ‘91 doesn’t look quite like that. The motor linkage has a smooth ball on it and the linkage has a blind ended cup. There is no metal tab on the linkage. This was supposed to be a simple job and now it’s driving me crazy! I know this is the 100 series thread, but I couldn’t find any existing threads on the matter in the 80 series forum. Perhaps I’ll start a new one there. Thank you for your help
Any tips on removing the ball joint from the bracket? Prying with a screwdriver didn’t seem like the right method.

After sleeping on it, I figured it out. Once the motor is detached from the firewall, you can manually move the wipers up the windshield. This moves the linkage so that you can deliver the joint between motor and linkage through the service port without trying to perform endoscopic surgery in a deep dark hole. Once the joint is delivered through the service port, you can get a good handle (and view) on things and pop out the ball without detaching the nut and losing your wiper park position. I used a flat head screwdriver which I insinuated between the motor arm and bushing. I just rotated the flat head, and the ball popped out.
