[Amc-list] Twin Stick shift knob replacements

[Tom Jennings <tomj@xxxxxxx>]

The twin stick knobs on my American were shot, all stripped out. I've been 
unable to find a replacement for the one with the pushbutton.

But MSC Direct (www.mscdirect.com) has "phenolic ball knobs" that work. One 
just screws on to the 5/8-18 thread (#00583740, $1.53 each) but is 2" 
diameter. The original is 1.5".

They have 1.5" balls, but not with 5/8-18 thread. You could bore one out 
and tap it yourself, the tap will cost more than the balls! The catalog 
page URL is below.

They have red ones too!

I made one of the 2" jobs into the "Twin Stick" ball with the pushbutton, 
it took about 20 minutes. I located the top center of the ball, drilled a 
1/8" pilot hole down into the tapped cavity. Chucked up a big (1") drill 
bit and used the 118 degree tip to make the depression (no pic here, but if 
you have Twin Stick you know what I mean; pics in the TSM). Then I bored it 
out for the button itself, I think it was letter U drill.

This leaves too much meat for the button to protrude; so I drilled some 
plastic out of the bottom of the tapped cavity with a 5/8" bit til it 
"looked right" poking through the top. Drill, test, drill, test...

OK, but with a 2" ball the button doesn't reach the switch mechanism. I 
simply cut a short length of rigid plastic to the length to make up the 
difference.


I also bought balls of other sizes to replace all the knobs in the car with!
