Henry's 70 Dart Swinger

My old one was a 3 spoke pulley and I found out later it looked like it was a typical BB pulley, mounted in small block brackets.

FWIW, Joe's first set of pictures, looks more like the one that's currently on my car.

you know i do see those three spokes on a lot of big blocks. i could have sworn the one i had was off a 340 duster. i just can't remember or find the thing.
