They will bolt right in- BUT- Note the thickness of the seat back rubber stoppers.
There are various thickness stoppers- When i installed my seats (also from a monte) they had 1/2" bumpers! That 1/2" equated to a very uncomfortable ride. Took 'em out, made my own thinner bumpers- problem solved.
That 1/2" at the base made a big difference how far the seat back leaned, and in an Elky, you need all the room you can get.
