New suspension making noise
 

so i got a new set of tokico struts and springs for my 02 ES and had them put on, the front ones are fine but the the rear make a clanky type noise like a loose bolt....i took it back to them they looked at every thing and said it was all tight and dont know why it was making the noise. The head guy called some one and they said it was probably the strut mount that i should replace the strut mounts when i use after market struts. Ive read a few posts that state they could be loose or not seated well but they said they looked at that, both be fore and after my return to them. Any other thoughts, and if it is the strut mounts any idea where i can get some that will work well with the tokicos.

the infamous rear end clunk....there are a few fixes out there....hate to say it, but do a search
