Need advice on replacement shift knob for 88GT 5-speed please! (Page 1/2)

Hey Everyone!

I am looking for a new shift knob for my 88 GT 5-speed. TBH, I wouldn't mind shortening my shifter by about 2 inches by threading it down the lever a little. But, for right now, I just want to replace the ugly Autozone multiple LED boy racer shift knob that it has. Are there any other shift knobs, like a normal leather one from another car that will fit? What is the thread size for the knob?

Thanks everyone!

I saw a few OEM knobs on eBay....

Other OEM 16mm x 1.50 Shift Knobs:
1993-2002 Camaro / Firebird
2009 to 2014 Dodge Challenger
2004 to 2006 Pontiac GTO

As aftermarket; search on Amazon and eBay for M16x1.50 Threaded Knobs or with "adapters"

If you want to cut the threads off from the shaft, then you can use an aftermarket knob with set screws or thread the shaft.

The stock Fiero shift arm diameter is too large in diameter to permit the use of most aftermarket knobs without extensive modification. This direct replacement shift arm has no threads and uses a 1/2" shaft.

I just bought this one from NAPA for like $18.00...

Exact same one on Amazon for $15.97....

It was a half hair too small for the shift shaft so i tool a Dremel with a drum sander attachment and opened it a little.

Work great now.

Tip: After you sand it, wait till it cools before sticking your pinky into the shifter. Don't ask...just take my work for it.

I believe it was Russ Wormuth (RWUpholstery) who was, at one time, rethreading Mitsubishi 3000GT shift knobs to fit our shifters. They were very nice.

2" polished aluminum from Twisted Shifterz, they have a huge selection to pick from in 16mm x 1.5 thread size.

Not at the present time, however, offers 'Leather Manual Shifter Knob' BUT:

Doesn't that get hella-hot after sitting in the summer sun for a few hours?

Yeah, I don’t want aluminum. Not a fan of how it looks, nor of the heat. Too Fast and Furious for me!

Thank you all for your posts though. I think I am going to shave my handle and go with aftermarket. The OE ones on eBay, even used are just ridiculously priced for the most part.

Prices on 'everything' have been skyrocketing and everybody is feeling the pain.......

I laughed at the price on this listing:

It's a bit warm for the first couple of shifts but it's really not an issue.
