Ratchet shifter
 

Hi. I need your help. I am looking for a ratchet shifter for my Camaro Z28 from 2001. In Germany you can not find that. I would like to switch the gears individually from 1 to 4. Just like in the youtube video. It is important that I can switch gear 1, gear 2, gear 3 and gear 4 singled. Can you show me a shifter who can do that? And show me where I can buy this? Many Thanks
