Gas tank for Will and Sarah,s van

Will is a quadraplegic,He had broke his neck 30 years or so ago. He learned to be a mouth stick artist and is very good at it. They did get pregnant and had a daughter, now with 3 grand children. Well there social security is not enough to make ends meet so they would do art fairs for his drawings to improvise their income, Any way the van they had bought years earlier had the floor lowered for his wheel chair causing it to rub a hole in the gas tank.The garage working on it can order a special order tank to fit. But $2000 is a big burden for Will and Sarah. My name is Ron Mclean Sarah,s brother asking if you could help them out, would be very grateful to you all. Thank you all for reading Will and Sarah,s brother in christ.
