Do you have enough movement of your secondary holder(by using threaded rod that holds it, swivel movement and tilt screws to center the holder in the draw tube? If you can do that first. then adjust your tilt to center the primary in the secondary mirror. Sorry if I am teaching you to suck eggs Alan
