No wonder you are having a hard time figuring out how to mount the drives. The Parks AZ8 is an altitude / azimuth (alt/az) type mount. It's movements are up and down in altitude, left and right in azimuth. The #93523 dual axis drive is for an equitorial mount, specifically the Celestron CG-5 mount. These type mounts are axially pointed to Polaris and the right ascension rotates about the polar axis. The motor drive allows it to track the stars at a sidereal rate. Those motors will not fit on your alt/az mount.

Very nice gift by the way! Send the drives back for a refund if you can, or trade the drive for some other accessories (eyepieces or a good barlow lens).

got it mounted on the cg5, but after leaving it sit for several hours, there was no movement of the scope, ie would not track anything.  sent clock drive back to dealer, they found the problem, some internal gear was not working.  got a new clock drive, but some how one of the mounts screw was broken off.  do not trust only one screw to hold mount, rings, scope, camera, etc.  took it to a machine shop and they could not get the broken bolt that is still lodged in.  had to send back to dealer.  good thing there is 6 inches of snow on the ground and temps in the single digits, or would be starting to get very upset.

 

maybe some day i will have a clock drive that works and is free of broken stuff
