      January 27, 2020 at 5:50 pm Logan, Unless your are an extremely competent and experienced guy with soldering, this is a very difficult piece to install…………………..You are dealing with thin brass and 14 Gauge steel sheet with many lbs of mass vs. 1-2 ounces of thin brass. Solder– 95-5 would be my choice.
