Tilt Column, a couple more questions

[custom10nut]

Ok, so today I finally got around to taking the hub off my Tilt Column.
(In my defense, I had to fabricate the bolts to work with my pulle)
When I got the hub off I found three large Phillips Head screws. Are these what hold the turn signal mechanism in place?
AND
When I remove this Mechanism, will I be able to access the three bolts that have loosened in my tilt mechanism?
Another question I halve is about the Steering Wheel mount hub.
How far down onto the Steering Shaft should the hub go on?
How much of a gap should there be between the cancelling cam, and the Turn signal mechanism?
I hope someone can give me some insight on these questions.
Thanks
