You may want to try an online site that only does selling.
I'm removing several posts a day right now.
If I open it up to that, it could get crazy.
I looked around I could not find if selling some items is allowed on this forum. I have a unifit adapter for a 14 inch rough in. I thought I needed the 14 inch adapter, but the supplied 12 inch was a better fit with the space, and I am over the 30 day return policy from where I got it.
