As stated, the OEM Ford Tractor "Hat Rims" were used from the 9N thru the Hundred Series Models. OEM was 9 x 28. Here are some pictures of a set I restored with my 8N Center Discs. The 9N & 2N used different center discs. The disc to rim bolts were a special 5/8-18 Carriage Bolt, only made by and available at Dennis Carpenter and Just 8NsMost every other supplier sells them as well as but nest to go with the quality suppliers. The new after market, 6-Loop Style is used nowadays and is probably the other style you have.
