looking for Doner HDPE for my husltler

[micmac]

I'm thinking about patching a hole that was cut in the lower by the PO to make a hitch. I know it's a shot in the dark but does anyone have a junk lower body section in the earlier green color Hustler. It looks like it's 1/4 inch thick and going to repair a section that 3" x 2" so I would need a piece slightly larger than that to trim to fit.

Also I tried to find a company online that sells HDPE I didn't come up with anything great anybody have any companies they use?
