Welp, got a call from The Champion Trike Technician. Told me that if on the rear of the "flange" if there was a NUT that the rear end would be a Toyota. If it was "threaded" it would be a Suzuki. Now to find some skinny enough to crawl under and look. I would do it myself, but once I am down, I have to call
9-1-1 to get up. Hope you guys know what I'm talking about. Not sure I do.
