Hi Andrew,
I am located in Southern Ontario, near London. The rims I looked at in London were identical. 14" X 5" rim size, with a 5 1/4" hub hole. They even had the same 3 three large holes around the edge of the rim. Good thing I measured the bolt pattern when I went there to buy them. Wrecker guy says he is sure they came off a Toy MH. I have since found 4 rims at a wrecker on Long Island, NY. I had them shipped to my cousin's place in Georgia and he will bring them up next time he comes this way (2-3 weeks). No customs issues. The wrecker guy in NY told me they were 7 1/4" bolt pattern. I sure hope he is correct. After I get my rims and confirm that they fit, I will check again next time I am in London about the others. If anyone else can measure their rims and let me know what they are, it would be nice to know if there is 2 different patterns.
Thanks
Ben
