Let's talk shifter handles and knobs

[jbtech]

Please school me on shifter handles and knobs. I'm sure others will benefit.

Take this handle I acquired for example. Was this a factory hurst T handle?

Which are the most sought after and how can we tell the difference between genuine and repops factory/aftermarket?

Are there Day2 knobs/handles that are extra special?

I'm ready to learn.

Thanks!
Jose
