Gas tank help

well i go and pick up my new 72 dart yesterday get it registered and start on my way home

i had problems with the car so i got it towed via flatbed to my uncles house

turns out there is a hole in the gas tank towards the top. not to sure on how big it is or were its at but if its pretty small is there a way to patch it for the time being

gas gauge doesnt work so were is the cheapest ones. Anybody have a tank on here thats in good shape?

im kinda strapped for money now that i just spent it all on the car and getting it registered. its still not at my house. like 200 miles away hahah thank god i have a ride to work well hopefully i have a ride to work
