When I tried to put the gear legs in the engine mount they wouldn't fit. First I thought it was the engine mount, so I measured the opening to make sure the opening was the correct size. Then I measured the gear leg. All seemed okay, but there was a little bit of powder coat on the two areas that make contact with the engine mount.
I spent about an hour with an emery cloth slowly removing the paint. I did not want to alter the gear leg size, so I took my time. Image two shows the two legs that now fit.
