I attached the EAF to the AT60ED via a coupling. However, I still need to install the bracket. 

 

From this image, which screws do I use?

The two silver allen bolts in the center of your photo. Due to the bracket being thicker you will have to put longer bolts in. Match them up at the hardware store and buy a handful of extra washers while you are there.

When installing the bracket be very careful your new bolts don’t screw in too far or they will bottom out on the brass rail on the bottom of your draw tube and damage it. If needed use those extra washers you just purchased to space the bolt outwards and dial in the distance.

Um...I would avoid the two allen bolts in the center, since those bolts actually hold the focuser to the scope.

I mounted my EAF on the WO Z61 (exact same scope as the AT60ED) using the two smaller threaded holes at the very top and very bottom of your picture, in the center of the focuser.  The small "plug" nuts in there currently do nothing to hold anything, they're just plugging up holes.  You can unscrew those, save them for later, and use the small 2mm nuts that came with the EAF.  Use a washer under them (above the bracket) so they don't go too far in.  That holds wonderfully well, and doesn't make you get new bolts to hold the focuser to the scope.  They're also not tension-adjusting screws.

thanks for that suggestion... ill check to see if i those screws that will fit. 

 

it seems without the bracket, the EAF wiggles like a loose tooth

 

i noticed you didnt push the coupling further into the focuser...i used a larger coupling so it would go in and then aligned the focusers hole with the coupling's hole...
