I would be happy to help!
The correct replacement wheel studs for your Dexter Hub and Drum Assembly 008-219-13 (our part number # 8-219-4UC3) is the # 7-257, and the compatible lug nuts is the # 6-53.
For a replacement silver wheel we have the Dexstar Steel Mini Mod Trailer Wheel - 16" x 6" Rim - 8 on 6-1/2 # AM20794 which is the correct size and bolt pattern for your 2010 Elite 3 Horse Slant Horse Trailer, but is a slightly different design than the wheel in your picture.

For a pre-greased hub/drum to fit the axle of your 2005 Trail Cruiser you'd want the part # AKHD-545-35-K and then for self-adjusting brake assemblies you'd want the # AKEBRK-35-SA which is a set that includes a left and right hand assembly. view full answer...
