Oh and if you need more head room buy the 480LM kit but it will set you back another 95 bucks or so. I contacted liftmaster and they said it won't work.. but I already spent 300 bucks and wasn't going to take no for an answer.

for reverse wound drums you have to flip the Lm3800 upside down and hang a pulley above it to reverse the direction of the release cable. Liftmaster doesn't make a model for reverse wound drums.
