Welcome to the Wicked Edge Forum NorCalQ. You can follow this upgrade Selection Guide to determine which upgrade kit 130UP2 for $320 or 130UP3 for $355 is the compatible upgrade for your model. It will depend on the year your ProPack was produced. The 130UP3 is for the older ProPack I and the 130Up2 is for the newer model Pro Pack I. This upgrade will convert your Standard Clamp Vice, (older style holder) to the WE130 setup.
You can also upgrade to the WE120 which will still use the Standard Vce you now have but give you a wider angle range and more precise angle adjustment capabilities with micr-adjustable rod arm ends. This upgrade is WE120UP2 for $150.
