New owner questions

[Dallas56]

I am a new SPF owner, roller 2895. 351 small block, stroked to 427 by Keith Craft, 580 hp, 590 torque. Love the car, big time.

I am working through new car issues, have been helped by many of you, thank you.

Two questions. First, my turn signal indicator doesn't work properly. For left hand turn, the indicator stays on through a full left turn without cancellation. For a right turn, it cancels with the slighest steering wheel movement, even before turn. Not a big deal, but I would like to fix it. Madmaxx, I think, advised to remove the steering wheel by popping the center steering wheel plate (using string, so as not to scratch), then unscrew the bolt, and remove the wheel, exposing the turn signal mechanism, which apparently can then be adjusted. I popped the center plate (with string) and unscrewed the bolt, but the wheel was still tight. What else do I need to do to remove the steering wheel and access the turn signal mechanism? And when I get there, with no steering wheel, how do I know which direction and how far to adjust?

Second, my speedometer worked prefectly for ten days, now has begun to spaz, wandering up and down when my speed is constant. Is this just a problem I need to learn to live with, will it resolve with time, or can I fix it now? If so, how?

Again, absolutely love the car, nothing like it.
