Water pump pulley in my 440 Dart

In another thread I am posting the restoration of my 69 Dart GT 440/727. Tin Cup is taking care of all metal/body work. I'm doing the mechanical. I bought it about 20+ years ago so a lot of the parts are pretty much what it came with.

The water pump pulley got damaged in the process of removing it. I am looking to get another one but the dimensions aren't the same as the ones listed for sale. My pulley is 2 groove and about 5 1/4" in diameter. The ones I see listed are 5 7/8" diameter. The depth is about 1 7/8". Anyone have a pulley with these dimensions or can steer me in the right direction?
