Need help with 93 LSD

[Dsandoval5]

I have a 93 talon and my rear LSD is clicking when I take off in 1st gear, and clicks even worse when I turn.I took it to a mechanic I know, but he couldnt find one to replace it. so I figured I could find one online for cheap, but I cant find one cheaper than $800. now few questions, I hear that in 93 the rear diffs changed, not too sure of whats going on. I dont want to buy one from a 91 and not fit, or it having different gears. anyways, this is my daily driver and I really need to fix it. if anyone knows anything about it, please get back to me. ive been looking and dealing with this for 4 months now. Thanks
