Hey I am using them. I have a 95 GT non vert. But I just put them on about 2 weeks ago. I have full bolt ons. and it works great with them. Look in the suspension section I talked about them in there. They are better then stock. But I dont know how they compare to other brands.
I picked a used set up $75
And It was easier for me to drop the hole rear end EXCEPT for drive shaft had jack under rear end. Then installed upper control arms, then installed the lowers. Most people say dont drop the hole rear end but it was hell for me when i tried doing one side at a time. and way easier to drop whole rear end
