take some undercarriage pics. what condition are the shocks in?....a "gas pressure charged" shock should help eliminate "bounce". my 2 cents: i love the kyb...performance, reliability, price...way to go. have had them on the 1978 2wd convertible since 1984. no luck with edelbrock, tokico, or rancho (monroe/tenneco). bilstein is great but pricey. gabriel is good for the $ & has been my most recent purchase for the 1983 4wd (purchased thru amazon & rockauto) the shocks replaced originals which had zero resistance in either direction...never seen ones that dead.
