suspension

hi,
I have a 1990 Integra GS and the rear suspension on the right side sounds like it isnt absorbing anything at all, it sounds like the chassis is straight hitting against the ground. so I am guessing this is the shock absorbers taht are dead.
So i need to find new shock absorbers, which one do you all recommend for my 1990 integra? im not going to be doing hardcore racing, but I would like my car to handle nicely since it already has 2 strut bars, might as well go a little further.

if you think it may be something else, please let me know

also, (**theoretically, not thinking of doing this, just curious**) if I only change the rear shock absorbers and leave teh front ones stock, will this screw up the suspension in my car?

any input would b greatly appreciated.
