ATC restoration

I have two older honda ATCs that i am truing to get running and they are so close to being done and i just need the fuel tanks and tires I need help to find replacement gas tanks for my two Honda ATCs due to them being left outside for 15ish years and rusting out. One is for sure a 1983 (first picture) and the second tank is from the shown atc. I cant find a year and again i need a fuel tank. Any recommendations for brands or other vehicles that have a similar/same tank that i could purchase? Thanks!
