half doors for the 825i

hey guys do they make a olive color half door or something similiar for the 825i.
We have the full enclosed cab from john deere but took the doors off this summer. Feels cooler for sure but not to safe without the selt belt on at all times. Yes i know you should always were your belt but sometimes when you travel short distance its a hassle. So i was wondering if some company makes a half door or something similar. Thanks
