The US Motor Works US5012 was the only one I have found. I bought two a coupla years ago when they were in stock as I was going to need at least one. I could possibly sell ya one of mine.

I would really appreciate that

Here are the two. I am thinking I should send you the one on the right as it turns more freely and has more vanes in the impeller. I am thinking of sending the one on the left to GMB for a new bearing and closed impeller.

And I'll send the gasket too.

I'm sending you the better one of the two. Better that you can just install and go rather than dealing with any issues out of the box. Who knows when I will get to my own install...

Now that I am looking at them more closely, are the impellers on the reverse rotation ones backwards? They seem to be the same as the normal rotation type even though they are supposed to turn the opposite direction.

Hope James will chime in with a pic of one the reverse rotation ones he has...

No. They're not backwards. If you look closely at the impellers, they're basically straight paddles that push the water around. So technically, the gussets for the paddles don't make a hill of bean's difference which rotation you have. They appear to be using the same paddle vanes for either rotation. It's the volute that makes the difference as it's a mirror image of the "normal" rotational pump.

In a few words...you are good.
