maybe the best way to find other shock absorbers for the b310 is to measure the lengths of the rear shocks when they're in the car,plus the length & diameter of the strut inserts.then take that information along to a
suspension shop,while it's quiet,& see if the
people there can find something around the same measurements & with the same way of mounting.this might get you something close you can use.don't forget to thank the suspension person by buying the stuff from him.
