What key cylinders are compatible for a 79 toyota?

I have a 1979 Toyota hilux pickup and it had the ignition key cylinder sitting on the floor board without a key. I need a new key cylinder but i don't want to pay forty bucks for a new one. I found several key cylinders for sale online that looked the same and they were about ten bucks. Any idea what years are compatible? 77-85? -88? Any intel would be greatly appreciated. Thank you.|||Try the '76
