Default Trex 450L servo size issue

Hello all,

I have a trex 450L 3s. One of my servos went out on me, so I decided to get 3 new cyclic servos.
my original servos are the Align ds416M servo. I could not find that exact servo so I looked up the specs of the 450l heli and the website said they come with the ds450 servos now. Ok so I ordered 3 of them. They just came in and they are longer then the old ones. See pics (it would not let me add pictures for some reason)



the new servo hits the main shaft with how much longer they are.
i could try putting a spacer between the servo and the mount. But I am worried the geometry will be off.
or I will have 3 servos for sell. And what servos would you recommend?
thanks for any and all help.

I use spectrum h3050 on cyclic. I see they are replaced with h3055. I have what looks like 1/4" clearance from the main shaft. As I look at the heli I don't see how a servo could interfer with the main shaft.
