QA1 rear shocks installation

with the QA1 shocks, the bushing width is 1/4" narrower than the ones that came off the car, also the bushings are bigger in diamater which make the washers I have too big! Wonder if Qa1 has solution for thicker and smaller outside diameter concave washers?....or a source
