the new one at 9" probably needs a smaller truck, maybe a 149. those fish shapes taper about 0.5" from widest point to the back...and about 0.25 over front truck, so you always get a bit of a magic carpet over front, but thats your steering wheel so should be fine.
this is all my best guess, and I also dont like my trucks flush with the the deck...so, someone else may have better idea on the truck size
