Hey everyone I have an oddball question, what is wrong with my seat?? It is a stock 89 GTA leather seat with two way manual adjust. It wiggles and squeaks like a **** (lol) it isn't loose at the base and both adjusters are locked. It makes this noise at any position, does this sound familiar to anyone?? Thanks all!

 

You might want to take out the seat and tighten the 4 bolts that attach the base to the seat itself. That might cure your problem--just might've worked itself loose over the years.
