Since the Storm Trooper has had a mahogany Grant #704 wheel
in it since the day I bought it, I tracked down https://cgautowood.com/
for a mahogany shift knob.
Their customer communication is terrible and it took 2.5 months to make, but they made a couple more at the same time, so they have some stock to ship. The product looks beautiful and feels great.
Naturally they use an M16x1.5 threaded insert required for the Fiero shifter. I had them recess it 1 3/8" into the knob so that it duplicates the height of the stock knob. I had them include a Pontiac arrowhead, although they could use a different badge, a shift pattern or no marquee at all at the request of the buyer.
The knob was stiff to thread onto the shifter. I bought these from Home Depot:https://www.homedepot.com/p...TMHX16X1-5/305502873https://www.homedepot.com/p...DWTT16X1-5/305699909
The die just took the paint off the shifter. The tap cut a nice pile of chips out of the CGAutowood insert, pic below. After I chased the threads in the knob, it spun onto the shifter very easily.
