it'd probably be a better idea to just get a trac-loc, limited slip, or whichever differential installed instead. they'll be a lot stronger than welding parts of an open differential, plus you can get units that allow appropriate movement when taking sharp turns and such.

You can weld the spyder gears. It locks the rear. Thats a cheap DIY mod that some 4 wheel drive people use. I would not do that to a street car or truck. Your best bet is to buy a posi if you want one.
I welded the rear axle in my truck. It's held up well despite some harsh 4wheeling. But then again, it's a 1-tonne axle that weighs about double that of a 9".
Works fine on my truck...only complaint is the increased tire wear. Expensive when new rubber costs $250 per wheel.
However, I'd never weld the 9" in my mustang. Welding the rear axle makes the vehicle corner like absolute crap. Not such a big deal in a lifted pickup that didn't corner well to begin with. But in would be absolutely horrible in a sports car.

im not gonna weld it for the simple fact that if i have to replace just one axle i would screw myself and have to replace the whole rearend, altho then i could get what i want 
can anyone tell me a rough price of a used trac-loc and how i can tell its it.

Well see... now your getting confused.
When you "weld the rear axle" you don't actually weld the axles together...or touch them with a welder at all. What you end up doing is welding the spyder gears. Either to each other, or to the carrier (or both).
Spyder gears are cheap, easy to find, and easy to replace.
You could always go with a spool. A spool replaces the spyder gears and acts exaclty like how it would if you welded the rear axle. Only difference is that it's easy to remove the spool later. Spools are cheap...less than $75.

Yes it would but you will also break axles. Welding the spider gears is what we did on our rockcrawler bronco 2 and has worked well. But it isn't street legal, that thing would bust axles hard after a day of daily driving. Spool will have the same effect, you really need to get a limited slip or my personal favorite a detroit locker. Locker offers cornering and such as long as you don't mash the throttle and will always lock up in a straight away and not break anything. Also it won't wear down, limited slip doesn't last too long.

Here's a great place to look and get great rearend parts.

Oh btw, Don't weld anything in your rearend, I've always tried to keep fire away from my rearend but sometimes you only have enough money for Taco Bell

Yes the lockers offer excellent traction, they will lock up just like a spool will. Just disengage at slow speeds around turns and such. It all comes to how much throttle you put on. You can lock it up from a stand still by mashing the gas and let it slip around the parking lot when turning by going easy on the throttle.

You can look at a powertrax, its about $400. You can install it pretty easy and it works pretty well if you dont mind the clicking noise.
Are we talking about an 8" or a 9"?
I would stay away from a Spool or Welded spider gears for a street car. It WILL make for strange handling.
Look at http://www.tractech.com/Products.htm for a lot of good information.
For a Street car a Detroit Truetrac is an excellent choice, it is a gear type limited slip.
Detroit also makes the Detroit Locker (Locker, Soft Locker, and EZ Locker) A true Locker contains a ratcheting type of mechanism and allows the axles to turn at differing speeds until power is applied. Then it locks up (hence the name) and acts like a solid axle or spool. The draw back is noise. (The soft locker is better)

if this was only a drag car, you could use a spool. but think about what youd be doing to a street car. u have to understand the dynamics involved. if both axles were connected together, everytime you turned your axles would be forced to spin at the same rate. well when you turn, the outer wheel is actually spinning faster than the inner wheel since it isnt traveling as far. so if you force them to turn at the same rate, can you see what will happen. one of the sides has to give which causing sqeeking tires and alot of stress on the axle. just not a good situation. spend the money and do it right, or dont do it at all. thats my opinion
