I have been online AND to local auto parts store and can not locate a window crank handle that fits our stock mechanical regulator on our 2007 Nissan Totan. Its the basic model and came with both power and mechanical window rolling up and down options. The power motors are not working and the handles on the cranks are missing. The universal ones that you find at auto parts stores are slightly too large. Also. There were black plastic fittings that made the regulator hookup size larger and you can either leave those on or off. Cant find a handle to fit that either. Help?
