Can't figure out these springs

How's it going everyone? First time here and trying to figure out what type of front coil springs I have? So I just bought this 2007 Tacoma 2.7 manual standard cab 4x4. It seems to just have the rear springs replaced ( I can tell by the part number spray painted on the spring and the paper tag on the perch) and the front coil replaced also by the part number on the spring itself and no paint mark like others have described.

It has the 4 leaf springs in the back and up front coils with seems to be spacers up front which look like 2-2.5". I want to level it out so I purchased Bilstein 5100 for the front thinking the fronts were stock coils. By the looks of them they are not. They seem very clean and have a part number on them, 50750 05 101 on them. Are these front stock spring by any chance?

I want to level it out and it is kinda. The front seem a little high compared to the back after I installed the rear spare. Does anyone know what kind are spring I have by the part number on them? I read on here that stock were painted in different colors instead of number. Any help would be appreciated!

 

Pictures are necessary for this one. Front and rear...and a close-up on the "spacers"

 

I’ll post pics of both the rear and front springs later this afternoon

 

Here are a couple of pics


I'm trying to level it out without the spacers, plus stiffen up the front suspension without so much nose dive when I brake.

 

Stock leafs.
Spacer on stock coils in front.

 

Alright thanks. Guess I'll be looking into some springs for the front end soon.

 

Do you like the height the front sits now, or do you want to lower it?
I have an 06 and just installed 5100s not to long ago. Find a set of coils taken off a third gen. I found a set for less than a hundred shipped.
The springs alone will give an inch of lift.
For the rear, I purchased a set of icon 3 leaf progressive AALs. I tow, so I wanted some rake. The 3 leafs add 1-1/2". 2" with the overload leaf installed as well. The whole thing was under 700 and took about 10 hours by myself.
It rides soooooo nice now

 

Thanks but I have a couple of 5100s here already and as far as the springs I'm ordering some 884's.

 

Probably want to replace that missing lugnut at some point too, just sayin'... Nice wheels and tires by the way - much better than what came stock with that trim level.

 

Thanks!
Purchased the wheels a week ago. Discount tire installed them and when I went to replace the brakes up front that one had to be broken off to get the wheel off. On top of that only 1 wheel was torqued down. There other 3 seemed lose. Called them and told them about it. They are sending me to a shop to get it fixed. They also retorqued the wheels after I tightened them.
