W2 / W5 Rocker Shafts

I have a set of W2 race heads I've had for years. With family priorities and limited funds through the years, I bought parts for my small block stroker recipe as I was able. I have 2 sets of Mopar/Crane rocker arms. One 1.5 and the other 1.6. The stands are available which is no problem. The original offset shafts (0.100) are no longer available through Mopar Performance. The old part number is P4120589. I'm well aware of the TD's, Jesel's and Harland Sharp offerings. I have a set HS on another pair of W2's. Having 3/4 of a Mopar/Crane set, I really don't want to spend $1,100+ for the high dollar pieces. I was wondering if any aftermarket company shafts are interchangeable with the old Mopar/Crane pieces. There's probably a pair of NOS shafts sitting on the shelf somewhere that were never loaded into the computer inventory. I just haven't been able to find them. Any suggestions would be appreciated. Thanks.
