i need a 07 vnl630 top bunk but cant find one

[loadlock]

hey there all, i bought myself an 07 vnl630 with a single bunk one year ago. i didnt think i was going to need the top bunk because i was planning on going solo. well it turns out that ive decided to take on a partner but i cant seem to find a top bunk for this truck, ive looked online and locally but ive had no luck. so does anyone know where i can get a top bunk with mounting hardware. any help will be greatly appreciated

Try a salvage yard I've found tons of parts here http://www.heavytruckparts.net/index.php
