Top Fuel Crankshaft

I built a stroker wedge motor some years ago using a top fuel 4.5" stroke crankshaft. The motor has been sitting in my garage unused for years. I've finally decided to do something with it. There are modifications to the crank required to accommodate a torque converter. At the time, I contacted Keith Black racing and they sent me the instructions required to modify the crank along with an adapter ring. Unfortunately I lost the stuff they sent and I can't contact them as their website is no longer working. Does anyone know where I can find what I need to modify the crank? Thanks!!

JW may have an adapter ring for the converter.[727 or GM converter?]

727 converter

There are several measurement that would help here like crank pilot hole depth,width ID/OD and I will give you my #'s

Thanks all!! I found the instructions and the ring.
