Helping someone in need

I am helping this lady who lost her husband 5 years ago and has custody of her two teenage grandchildren. Her late husband took care of all maintenance on her 5 acre property , vehicles etc. She is older and currently unable to work due to a heart condition but she’s all the two kids have . A group from my church and I have been going out to her property to clear overgrown bushes since I met the lady in September . She has one vehicle that is in need of some repairs to make it safe and street worthy . My church is donating $300 towards the cost of repairs but we still need $600 to get tires , balanced , mounted and aligned . My friend and I are donating labor and money toward the axels and tie rods and we are going to do the work there but need help funding the tires.  I know it’s been a rough year for us all and I’m only asking if you can help, she would truly appreciate it and so would I. Thank you and God Bless .
