sn95MustangGT

So I have done suspansion work to my pony and here is what i have: H&R Sport Springs, Edelbrock Shocks R&F, H&R +trac 30mm spacers at rear, Stage 3 Roush lower control Arms. What i have just noticed is that the rear does not sit aligned with the axle after putting the spacers on the car and there is an about 3/4" off set to one side. I am doing some research now to see what can be done to fix this and a Panhard Bar looks like it is the best option to fixing this. I have looked on the forums but no one has which Panhard abar to use nor which bar is the best; pro's and con's of each bar, or going with a watt link system or would that be a waste of money? And where would i be able to get the bars at a good price. I have a 1995 Mustang Gt. Any info would be good thanks.
