I am pulling the transmission to replace the throwout bearing, but to pull it out I need to drop 3/4 of the cradle mounts. I usually jack my car in the rear by the cradle, but obviously cant do that. I know theres that image with the jack locations, but it is way too vague. The red points on the image there is literally not enough space to put a jackstand there.

Can someone post an image showing how they jacked their car? All I see on the internet is people using a long 4x4 across the entire car, but I am not doing that.

Well.. id say still jack it from the cradle but support with the stands not on the cradle. You should never get under a car thats not securely on stands.

Edit.
I use the 4x4 method when dropping the cradle ever since i dropped a couple Fieros off of stands doing cradle work. You don't jack the 4x4 you use it with stands to supplement support. Prior to that i would support with stands in about the same place but if the car shifts those stands will fall and drop the car.

I apologize, I meant where do I put the jackstands to support the car to work on it. I am using a hydraulic jack on the cradle to lift up the car to start with.

On the red points, my jackstands cant support it in the middle without colliding with the coolant tube, and I was wondering if there is another point near it that I could put them

I'm not sure if you made a mistake with the colors. The green is how you are jacking up the car right now by the cradle. The PINK is the jackstand locations and there are many of them. They are labeled "safety stands".


But to use the factory jack locations (in red), most people do this:

Oh Yeah I misunderstood the labels, on most cars the pinch weld is where you could put a jackstand so I assumed the same with this car. Also, is this a suitable jack stand location? It looks like this is one of the pink spots on the diagram.



This is the front left subframe mounting spot if you couldnt tell, there is a curved lip on one side which looks like a stand point. on the other side there is a coolant line in the way but its rubber so I should be able to push it out of the way.

I lifted my Fiero and mounted it on jackstands positioned on the frame rails just forward of the cradle forward-mounts...Then supported the engine (With Fiero store engine support) and dropped the subframe, and then dropped the trans (But not on my head (Slowly learning from past mis-takes)

I removed the rear wheels and set them (Basically) in the frunk for better balance.

Here is a quick pic of where the jackstands go ;

We have used the jackstands in those spots for years with no issues.

One thing I always do now when using jackstands; After they are in place and I have lowered the car onto them, I lower the jack approx' 1/8" below the frame and then I stand to the side and jerk on the car to make sure it is solidly supported. Once, when I did this, the car slid forward slightly- I had not repositioned the wheel chocks after jacking (At the top of the jack arm-swing the car can be moved backward- moving it AWAY from the forward chocks- Just kick them backwards tight against the tires BEFORE Lowering)

Always use chocks front AND back on the GROUNDED tires when jacking.

Also if you are curious, I was following this guide:

the beauty of using a 4x4 is that you can use jacks on the ends to raise and lower, and if you use pieces of 2x6 like me you can safely support to just about any height.
I place a hockey puck between the frame and the 4x4 to assure nothing slips, eh?
BTW, I am using the same support points as others, as has been indicated in red in their pics
the jacks you see really don't do anything, they were just placed there for additional security, normally I remove the tires and then use the jack stands on the lug bolts as an additional raise/lower support point
I knew somebody that was killed by trusting jack stands, ... so I don't

I don't trust jack stands either. However, with the setup you have there, I'd be quite leery of any lateral force potentially causing the stacked wood to collapse off to either side. EDIT: I didn't even notice the jack stands in the middle. I guess your setup would be okay, but I'd still feel more comfortable if I was under there with the wood arranged in the following manner...

Easy to make: use 2x3 lumber, wood screws, glue (PL Premium or yellow glue), and red Tremclad (colour is up to you)
Not overly expensive either.
When supporting the pinch weld section below a car's rocker panel, the metal will bite a bit into the wood; low risk of slipping! Do orient the pinch weld perpendicular to the wood grain to avoid splitting.
When using these blocks on asphalt, the large surface area prevents sinking into the pavement.
They're quite strong enough; I have no qualms about getting under a car supported by these.
