need help finding the right brake shoes..

[Skarekrow]

I'll attach a picture.. but i have NO IDEA what this bike is, or even if all the parts on it came from the same bike.
everything is working fine, but the brakes. I would love to get new shoes, but that is a task that is proving difficult, without knowing the model number or make of the bike..

so here are the dimensions of the current brake shoes:

Front:
Height: 3.3" (83.82mm)
Width: 3.3" (83.82mm)
Installed width: 3.46" (87.88mm)
Depth: .8" (20.3mm)
Front drum ID is 90mm

Rear:
Height: 2.86" (72.6mm)
Width: 2.9" (73.66mm)
Installed width: 3.05" (77.5mm)
Depth: .72" (18.28mm)
