On some or this forum Jack in Alaska had a complete report on how we did his with pictures I think. The track needs to come out. I bored extra holes so we could screw where it was easier not just where the original holes were, It was a 2 man job with the Jacks engineered tool setup. I hope Jack can report to you. It was a tough job to remove the door because the opposite wall didn't leave much room. the hand rail had to be removed. Just for information if and where you remove the track be sure to re install the rollers with 2 of the 3 rollers on one side and with the other having the 2 on the other side of the track or it will hang out of level. I am guessing yours is the same company as Jacks or what we have on the alpenlite for hardware.
