You are going to have to be a bit clearer in your description.
If you hold the spur while also holding one of the "rear" wheels, the other "rear" wheel should not spin freely by hand. What should happen normally is... if you hold 1 wheel and give slight throttle, the other wheel should spin under power. This is how a differential works. You can also hold the other wheel and do the same slight throttle and the free wheel should now spin. If not, your diff is too loose or damaged.
If the suspension is set correctly, none of the wheels should lift off the ground.
Do us a favor and set your car on a table and take a close picture from the front and rear of the car showing how the suspension is set. A picture is worth a thousand words.

It won't let me add links, says I'm not allowed...
Search me on fb Angel Kamirov, I have a public folder set called rc stuff.

The left wheel should not rotate without forcing it under that situation, you may need to tighten the diff. Even a properly tightened ball diff will slip if you force it hard enough though, how hard are you twisting it?

If you hold the spur gear and turn one wheel in one direction the other should turn in the other direction. If you hold the spur and pinion from turning and push the car on a good grip surface and your wheels turn, as opposed to skidding, your diff is to loose.

I've uploaded some pics to my profile.
And yes, holding both rear wheels and turning the spur gear, did in fact have free rotation.

Just going by eye on those pictures, it looks like your front left wheel is possibly partially raised, sitting at rest. Check your droop screw isn't jacking it up a bit.
Also, try tightening the rear diff. It may need a rebuild if it has been run that loose for a while.

I'll tweek around the droop screw and see if that makes difference.

After making adjustments, it still pulls left, especially when I really get on it.
Also, can the same diff that is in the rear also go in the front? If bought new ones?

Front & rear diffs are interchangeable.

You can adjust the upper turnbuckles to fix this.
Also, find the center of the front of the car & mark it, then slowly lift the front up to see if both tires lift at the same time. Adjust spring spacers & droop as needed. Repeat for the rear. Simple tuning trick to use as apposed to buying tuning tools.

Do I need to extend the them or retract so to speak?
By the way guys, I really appreciate your time trying to help me out with this. It has been a pain in my arse. All I want to do get practicing again and maybe get back into racing.

The outer edges are off the surface. This means you need to extend them.
Thanks for the appreciation. You're just living one of the joys of buying used.

Alright, I made the adjustments on the buckles, which did help a little and also changed the rear tires which ended up improving the cars performance by a lot. A little more fine tuning and I think she will be good to go.
Yessir indeed, it was worth it though, just needed some work, time and patience.

Yeah I'm gonna work on that some, they seem a little tight. Too much oil in them I think.
