The T6 and T7 use completely different circut board layouts and power supplies. Thus the cost to upgrade a T6 to a T7 would salvage only the chassis and switch wiring, not an economical prospect. You had ordered the T6 rebuild kit plans. If you purchase the T6 kit and built it very neatly, and then want to upgrade to a T7 in the near future, we would allow you full price for the T6 kit back in trade, assuming you wave the satisfaction guarantee (you don't get that on a do it yourself kit in the first place). A messy kit wiring job would depreciate the trade in value of course. Frank Van Alstine
