I recently bought a 405000x8 (2005) and it's simple...2 bolts/2 shoulder nuts hold hood on. 1 large screw is the blocker. Could add another blocker screw to the other side if too wobbly. View attachment 54599
It seems that I have an older model (2002) Murray SELECT, model #425009x31A, Widebody. 16.5 hp, I took photos of the spring and attachment hook but unfortunately I wasn't able to attach the files because this site said that they were too large. Sorry, I don't know how to reduce the size of the photos. Thanks!
