2004 Mazda 3 Rear Strut Boot

[JamesMeiser]

I bought some after market rear shock absorbers. I installed them a little over a year ago. Well, now the strut boot that protects the shock absorber has worn away. I can't find just the strut boot anywhere. I called Mazda and in order to get the boot, I have to order the whole shock absorber, which I don't need. Does anyone know where I can just find this rubber strut boot? Thanks.
