I have an older Cobra trailer (1980ish - aluminum) and need to find another
tire rim (I had an axle mishap and lost one of my tire/rims). The rim is a
4 x 100 metric (four lug holes and 100 mm between each lug) and supports a
13 inch tire. Does anyone have a rim for sale or can suggest a source in
the US hopefully close to Atlanta, Georgia to get one?

Thanks for your help.
