Replacement Wheel for Ampeg 810?

[Superdave]

After the last gig the band played, we were moving the cab around and one of the wheels cracked right off. The actual frame for the wheel is intact, but the plastic wheel itself is gone..

It's an 80s Ampeg 8 10, I'm assuming because there is no input for a speakon.. Has anyone replaced one of these before? Any recommendations?

Thanks!

I think fliptops.net has them, I ordered one a few years ago.
