When using a rear mount snow blower on my LX3310, I could use the two side mirrors when backing up so didn't have to turn sideways in the seat so often. I did have to turn to see directly in back of the tractor until now. I mounted a 16" panoramic mirror, that I got on Amazon, inside the cab. I used 1" square aluminum tubing to mount the mirror to. The long tube is attached to two 2" long pieces of tubing. The short pieces of tubing have three sides cut off so the headliner screw goes through the tab that is created. Between these tabs and the headliner are two plastic washers, on each side, to take up a slight indentation in the headliner. The headliner screws were a pita to get back in so I ground a taper into the ends of them and then had to apply pressure while screwing them in. I used a long allen wrench to find the hole that the screws threaded into and to be sure nothing was in the way.
