3. Attach the new adjustment collar plate.

5. Mark, center punch, drill and tap 2 holes wherever you want the worm drive. (I chose the back to make it look OEM)

This took my about 1.5 hours. Make sure you have good drill bits. I snapped 3 bits just drilling into the collar.. This is a pretty easy mod. If you own a stepped Macap I highly recommend this mod! Total cost for parts $70.
