Hi, My friend and I are going to install new shocks/struts into the following cars 1990 V6 and 1987 4cyl Camry wagons. We are thinking about installing KYB shocks either midrange or performance. One thing we can't quite get a clear answer on is how do we tell if the cars have servicable struts or not? We see on KYB's site that they sell both sealed and servicable. We want to replace the stock struts and shocks so do we have to buy servicable or can we just buy sealed? Which is better and why? Any thoughts on this would be very appreciated as we want to order the right parts before ripping everything appart and then finding out we have the wrong parts. Thanks, Bruce
