Dear Metallo,

Hope you're well. The photo is helpful as are the dimensions. As I do not own / have not owned any 960 or S/V90 car, I'm not familiar with the rear suspension on these cars. Does the lower shock mounting bolt pass through these washers, and so separate the shock bolt steel tube's ends from each of the metal "ears", welded to the frame? Thus, are these washers "sandwiched" between the ends of the shock mounting and the mounting ears?

If so, it should be possible to find a rubber hose, with the correct internal diameter - likely the most critical dimension - and to cut a cross-section (slice) of the same width as the factory-installed washer. An example: Volvo heater hoses, if I recall correctly, are 5/8" in internal diameter and pretty close to one inch in external diameter.

Or, does the shock's lower mounting end with a threaded rod with a nut above and below a mounting plate? Do these rubber washers separate the upper and lower nuts from the steel mounting plate? If so, then the rubber washer is load-bearing and must be of the specific composition needed to bear the weight. A washer of the dimensions cited likely would not have the load-bearing capacity require, unless made of a very stiff rubber.

Hope this helps.

Yours faithfully,

Spook
