Back halfing my 74 Scamp

I have considered installing one my self but I have serious issues with trusting my self to get it right and making it just like a pro done it. maybe that's a good thing I don't know. I have never done anything like that before> my metal working experience is limited and my welding is ok not perfect. I am about to invest in a new more powerful mig welder big upgrade from my HF 110 welder. Anyway thanks for the advice I think I am going to order one then see if I feel comfortable installing it.
