Power director for pulling

  Purchased this 7580 PD from a puller while back finally took it apart, he claimed it was used one season on a thousand horse tractor. As you can see he took high side clutch and gutted the insides and continued the separator slots so they meet the low side slots. Stacked inside a total of 12 plates were used, I discovered the three very center clutch plates slipped and warped.
 Question for Doc and others, too many plates so the piston couldn't travel far enough to fully compress them??? I figured remove three and shim up difference?  My calculations are .404 separation per clutch and separator plate, does that sound correct?
 I started making second PD from 7060,the most challenging part is finding a shop to weld the high and low hubs together, could machine new one, very spendy! Don't know if you can see in photo the smaller low side splines were removed and only engages high side. This new PD would have 7or 8 plates. Also could leave low splines on and remove gear on back of low shaft, maybe?
  Another puller on this site is considering this set up also, so comments welcome.
