I have a Girard 2000 awning. The motor runs but it sounds like gears are striped. The gears are most likely nylon. Have any of you folks changed out the motor and if so, are there any tricks to the removal and installation of the new motor? Has any one found a different source to buy the motor. Girard quoted me a price of $600 plus fright for just the motor. WOW<br/><br/>Thank...
