I’m just south of you in Warner Robins and I have a 53 MGTD kit that I’ve been building. The assembly manual might give you times for assembly but take that with a grain of salt. Just fitting the hood on mine took several hours of adjusting the fit. But overall, my guess would be between 8 months to a year. Actual hours spent assembling would be more like 2800 hours.
