Wayne, not about the T5 swap, but you will like the Woodward gauges, I have them in my T bucket and love them and how they work, very accurate to boot.
Good to know. I want to have the tach built in and there are only a handful of companies that make the dual 3-in-1 type of gauge. More are coming out all of the time, but when I found these, I liked the style, how and where it's made, and the price. I also like New Vintage USA's 1940 Series line...like this -
