As far as the process its easy to do, they are set up the same way, the springs are stacked the same way all that changes are the lock ring and the piston.
To change from LP to HP follow these steps
Step 1. Remove the two set screws on either side of the tank reg
Step 2. Use a 15/16 socket to remove the lock ring and counter clock wise until the top can be removed.
Step 3. Remove the piston and springs from the reg, switch out the piston for the one you want in there (HP Or LP), be sure also replace the lock ring as well.
Step 4. when placing the spring back onto the piston be sure to place them in the proper configuration as shown in pic
apply some dow 55 to the o-ring on piston as well.
Step 5. Be sure the valve pin is placed back into the reg top, screw it back into the reg (wouldn't hurt to add a drop of blue locktite before screwing back in) and reverse the process from step 2.
