I didn't glue the bezel to the backing plate until I made the curve and was satisfied with the fit. Also, I used my original as a guide for the bend and improved it a bit with a wooden dowel. Then I put the backing plate onto the plastic housing first and glued the bezel that way. Even bought a 6" C-clamp to go over the left 90 degree side so I could put pressure right in the corner. I was really paranoid about getting it right, so don't feel bad. If you do a thread search you'll find more info, this has come up before....Good Luck
