It should be some angle at the rear hinge.......aim at/from the front hinge, both hinge pins should
should be in the same line.
About the rubber and the bracket don't line up.....all three mountings under the seat you can adjust a bit
after you have loosen the screws.....I suggest that you glue the part together and try to mount the seat
w/o having tightened the screws fully.
I have glued these part on my LT, but don't remember which kind of glue I did use....think it was a
cyanoacrylat based express glue.
