If you have a DK98 press (curved handle and curved back), you can use the dies for DK93 by installing the die adapter.
DK98 dies are shown on the left; DK93 dies are on the right. As you can see, their stems are different. The DK98 bottom die (2nd piece from the left) has a stem that is more narrow than the DK93 bottom die (last piece on the right).
The die adapter is a sleeve which will allow you to use the DK93 bottom die with your DK98 press. As shown below, the original adapter sleeve in the DK98 press has a smaller hole to accommodate the DK98 die. Our die adapter has a wider hole that will accommodate the wider DK93 bottom die.
