I recently moved my pool and found that some of the bottom rails are rusted. I lost all of my pool info in a house fire last year. Where can I find these types of replacement parts?

How large of a poll are we talking?

the pool is a 12 x 24 oval above ground pool,

Your best bet is to replace all the rails with any brand that will give you the shape you currently have.

I know what I need, however, it is next to impossible to find someone who will only sell you pool parts. I have found inyopools.com then type in "muskin" it will bring you to a site that sells replacement parts for the entire pool frame.
