dont replace the bushings... replace the entire arm.
Dont be fooled by companies selling "low budget" control arms... or the cheap sets that can be found for $150 or even less. Lets use these as an example.

these control arms, while strong, offer one of the worse bushing designs ever. The hard poly bushings will increase the suspension bind inherent in the psuedo 4-link that the mustang has.
If you are going to be doing street driving, you WANT some flex in the rear end. The poly bushings stiffen up the rear so much that it can actually DECREASE traction by not allowing the suspension to do its job. In the case of a street driven car, or even a entry level road course driven car. It is wise to leave a stock set of upper control arms. You can go with a set of lowers like these.

Now, if drag racing is your thing, and you drive the car on the street... then I'd recommend this setup.

If you plan to drag race the car, and really need something to get the power to the ground, I'd suggest you go with setup like this.

IF you do decide to go ahead and replace them look at the body end of your lower control arms. I think stock they are all oval on that end.
But as already said, don't waste the money. UPR sells some nice lowers for a decent price as well.

like i stated above on my suspension stuff i am going maximum motorsports i am thinking about saving up just to make it easier to figure it out but thanks for all the help
oh i am not being thick headed i would replace them gladly if i had the money i am trying to get rid of the noise in the rear end when i let off the gas i know it can either be the u joints or the lower control arm bushings so that is why i was only going to replace them but i am considering saving for a couple more months.
also i plan on making this a street, strip and semi road race car which lower control arms should i get from maximum motorsports and does any one know the benifit of the adjustable spring perch

Yes, it is very close.
One description:
This feature allows you to raise ride height by 2" or lower ride height by 1". This is especially useful for clearing taller/wider track day tires & then being able to return to a reasonable ride height for your street tires.
MM's description:
The easy adjustment of MM's Adjustable Control Arms allows raising the rear ride height by up to 2 inches, or lowering it as much as 1 inch. A heavy-duty weight-jack bolt, similar to those used in NASCAR, makes this possible. The spring perch design allows easy ride height changes, with the car still on the ground. Road racers and autocrossers can set not only the ride height, but also corner weights, for optimum handling. A car can be fully loaded up with gear for a road trip, and then have the rear ride height adjusted back up to normal, to avoid bottoming out. These control arms are available with mounts for a factory-style rear swaybar, or without any swaybar mounts, for use with MM's Adjustable Rear Swaybar.
There are many reasons for it but yes what adder said are some of the more important parts about it that are not described but the people who make and sell them.
