Caliper rebuild kits

[shadowmagic]

So I ordered the two kits for the two front calipers. My question is, are they interchangeable with the rear caliper? Upon further inspection I realized the noise is more pronounced in the back. I would like to use one of the kits to rebuild the rear and then at a later time order another kit and do the two front ones if I don't see a dramatic improvement in sound. Thanks for the help!

I think front and rear caliper piston
seals are the same part number unless you have an
Interstate...
