i need to replace both of the from drum brakes and im wondering how much will it come out to be, or is it better to do it yourself?

When you say replacing, you mean just new linings and drums or doing a disc conversion. If its just replacing the drums and shoes. I dont think it would be that much. Just call a parts store and get a quote. Also check if you need to replace the seals and bearings.
