Hey Guys
I sourced an original band clamp from another TEAE club member. It cleaned up nicely and will go on the car.
That said, I also pursued rebuilding the original. I used the AH clamps recommended by Sean.
Upon receipt, I trimmed the length down to a similar size as original (I gave myself an extra 1/4 inch.) I thin looped around the wire bracket, inserted the other end through the cotter pin and then tightened everything down.
It looks pretty good. Give that shiny band a little patina and you would be hard pressed to tell the difference. Thanks for the tip. Hope this helps somebody down the line.
