Can anybody tell me a source of a shift knob with the correct 6 speed pattern on it or tell me what threads are on the 4 speed shifter that was modified for the 6 speed? Thanks
I got home at a reasonable hour and my new shifter knob was waiting for me:
It was $16 on ebay and had the right shift pattern for the F40 - its for a VW. The install takes some work as the shifter knobs snaps in place on the VW and I needed it to thread into place. Here is an underside pic:
I cut the tabs off and used a large drill bit to bevel the area (the knob material is plastic):
To tap it for the M16 x 1.5 thread, I ended up running a .55" drill bit down the hole to enlarge it slightly. Next I ran a .63" bit down about 1.5" to allow the knob to slide over the shaft. Last I tapped the bottom of the hole for the shifter shaft. Here is an installed pic:

The only issue I had with that cheapo knob is the pattern disk came loose. So I used some black RTV to glue it back down and it has been fine ever since.
I don't get around these parts much any more... But figured I'd chime in on this one - I have the same shift pattern in the Lotus, and used this engraved 2" stainless shift knob. It does come in M16x1.5 thread, and you can pick the color of the powdercoating in the pattern. Definite down-side is it's almost $100 shipped..

So the portion you threaded was plastic and no problems? Looks good I will check Ebay.

IF I had a Lotus I would go for the same knob. I will check them out.
My input is the size of the shifter ball. When I went to make the first Sport Shifter for my 88 Mera i bought a Hurst 2" shifter ball. In my opinion the 2" shifter ball is just too large for the Fiero interior and in my opinion looks out of place. So I use a smaller shifter ball on my Sport Shifters. 1 3/4". A 1 3/4" shifter ball looks more in tune with the smaller Fiero interior.

Be cautious with aluminum shift knobs. They get very, very hot in a parked car during the summer (ran one for several years).
After 8 hours in the sun with the top off I swear I could brand the shift pattern into my hand.. Don't forget FREEZING cold in the winter too.
When I had the Fiero I ran a Grant Evolution shift knob which I thought was proportioned pretty well (and plastic), no shift pattern on it though. I tried it in the Scion and the Lotus and it feels way too small..
Check out the 2014 Ford Mustang shift knob. Wrong thread, it is a M12x1.25, but very nice looking and can be found cheap on ebay. It is what I will be running in my 6 speed swap.
