Well U if they are original shocks I'd probably think about a new set, they are 25 years old now and even if they have some functionality left its odd's on that both sides will be different. A good set of spax adjustable will sort you out and I think you'll find the improvement worth the cost and effort. Cain at wolf performance has just developed a rather tasty option too and they are very competitive price wise..... they weren't only designed on a drawing board either!
