Need A Handicapped Golf Cart

Playing adaptive golf comes with a lot of challenges.  Finding adaptive carts is very difficult as they are not mass produced like standard carts are.  The company that made the pictured cart went out of business about 15 years ago and finding parts to keep it running is almost impossible.

I am in a wheelchair most of the time.  My exception is when I am on the golf course.  Without an adaptive cart, I am unable to play the sport I love.  I will lose one of the biggest forms of relaxation I have.  This is why I am asking for help.
