Ok I have looked around for an answer to this question but can't find one -

If you have Cluster Missiles and Danger crew, can you use Dengar on both attacks of the missiles or only one, just can't find it in the FAQ. If the answer is in the FAQ can you tell me the page number please.

If it help's Dengar will be part of the Crew on Morolo Eval's ship with a K4 Security Droid and an Outlaw Tech also with HLC

Yes you can use him on both Cluster Missile attacks because they are separate attacks and he can trigger for each attack.

Dengar crew resolves in "Attacker Modifies Attack Dice" (Step 3.ii on the new Timing Chart), which is one of the steps that does happen twice in a PTAT attack, so yeah, there's no reason he wouldn't be usable on both.

Awesome guy's for that, going to try this out tomorrow

Use the cluster on Bosk with chips ... Dengar of course. 4 hits in one volley.
