Just to make sure you understand: There’s only one stop - the one that keeps the pedal from falling toward the driver’s seat. Ultimately, the clutch pressure plate springs are the stop that keeps the pedal from falling forward toward the front of the car.

As others have said, the clutch pedal is held in the upright position by the action of the release bearing return spring pulling on the cable; there should be a stop post (on the TC it is a bolt in a sleeve) welded to the front of the bushing the pedal is welded to that keeps it from going any further (check the manual for how the pedal is aligned).  Sometimes, that little post is worn down/broken off...so...if worn, I just drilled a hole in the floor and installed an AN3 bolt to account for it.  Doubt the new owner even notices it...broken?  I think you'll need to add a little piece of rod...

When you depress the clutch, the total travel will be regulated by the limits on the throwout/arm against the pressure plate.

  I rebuilt and plated my pedal assembly and added a lube channel into the shaft years ago documented here :

   I just can’t reach it right now . 😃. I have to install my oil pressure gauge, mount facia , rehang column and hide wiring . Remove a few extensions I added to the DB10 relay to test everything.
 
   Tried to install the gearbox today after shopping for concrete pavers and concrete bags plus a few 2/10s . I could not lift the gearbox in . 😅. I’m just getting too old for this. I’ll get it in tomorrow after a good rest.

I've had my tranny out probably half a dozen times and I think until the last two (which were in the last two months) or three times I've had help. Maybe I can still do it but maybe I'd would hurt myself. Like most things, it's better with a friend.

I don't always remember to do this, but it's a nice idea to put a little grease on the splines of the input shaft to help it go in (staying away from all sorts of comments here! ;) ). I wouldn't say it always makes it but it might and won't make it harder.

I've found that once I get it in the car and generally in place, it takes a lot of shaking, wiggling, cursing, staring, pulling, and pushing to get it engaged with the clutch plate and it's pretty heavy and unwieldly to do all that to it. When you're close, you can pull it to the engine the last 1/2" with the engine to bell housing bolts. Be careful and remind yourself that you're screwing into aluminum so don't use much torque when doing that. If it takes a lot, it probably need some more coaxing.

I use a floor jack to hold it in position. Once it's in a little and is generally supported, sometimes someone underneath it can help coax it. I thought of using an engine hoist but I don't think it would have helped me.

Good luck!

  First thing in the morning with the aid of a motorcycle tie down strap to teeter the gearbox
I was able to muscle it in in about 10 minutes. Whew , now to get moving .

TEN MINUTES!! That was easy! I guess not having a fifth gear makes it a lot easier.

Good for you!

      It was definitely better than trying to use jacks I don't think I would have lasted much longer, having the alignment awls also helped. Gavin's method of ramping up the back was what was able to be achieved, basic bootstrap method. The temps here are so refreshing. we hit a low of 60 degrees f.
 Next time I will be setting it up under my ceiling hoist. I'll be testing all the problems with this one before testing a standby one I purchased.

   :FUNNY:   Turbo, I clean things once.
   
  Anyway, that might not be the gearbox that's staying in it. After draining the oil out, I discovered allot of silver particles when turned upside down and vertically.

  All back together and back on the ground, except for the pulley adjustment for the water pump. Saving the roll pins for another time.

  Which reminds me to bleed the coolant system.
Putting the dash back in and rehanging steering column.

That tranny can't by yours. It isn't polished!!

What is the central mount thingy bolted to your cross member? What does it doe (if it's not a mount) and why do you need it? Isn't your tranny mounted in the rear?

It looks like a scissor Jack.

  That’s correct silver. I mounted it there so it doesn’t slide all over . Not really necessary to hold in the boot or bonnet area. I posted that on my thread years ago.
   BDA , slacking a bit lately here, too many other tasks coming up . It may be pulled soon after I road test it. I have a spare and will cycle it in to test it. 
 Then the other engines.🥱
