yep
all you got to do is unplug the eyes and solenoid (i think thats all - easy enough anyway) from the board, unscrew the frame, taking off the reg and put the UL frame on, plug in the cables etc, nothing tricky
programming on the stock board is VERY easy, not sure on UL board but i would assume its not difficult.
maintenance is easy, only takes a few minutes to relube bolt / reg on a PMR
