my only complaint about this baseplate, (well, i had to seriously mod it to fit the car, but it is an oddball setup, so i can't complain too much), is that there is no real 'lip' for the gasket to attach to. i only had about a 1/4" on most spots to attach the gasket, which is not a lot, if you look at the side profile of the gasket. so, a lot of patience, a lot of weatherstrip adhesive, and we got it. i'm happy!
