clearance is barely but i can live with it hehe. when in 3rd and 5th its still possible to switch cds, i just have to take my time . as for the mounting, it's fine now but i'm gonna secure it somehow but i don't know yet, lol. it's fits perfectly in there though. there is a bracket that holds the stock radio thats has a screw just behind it. i had to take that out and it sits right in top of it. i also dremeled the HU in a almost perfect fit.
