It will make the job way easier, I’m not sure if you have to cut the caulk on that top cover piece to get to the remainder of the track though. Pull the screws from the remaining track on both sides and the top door pulls right out. I take ours out yearly to clean and lube the trucks, takes 10 minutesGoing to attempt to replace the cabin door track on our 2000 410, wondering how and if the door needs to come off as it looks like the track runs beyond where the door slides into.View attachment 133291
