If you have a manual, there's a way, that a Member of this forum, did to the gearshift to, make it work with the lower console, without going through the process of transferring to an automatic.
Check out this YouTube video by, the YouTube user:
KN1IGHT - YouTube
The YouTube video, I can't find right now, 'cause KN1IGHT has a lot of videos.
But I do know, in one of his videos, he explains his gearshift, as his is a manual, and what he did to modify it.
Essentially, it's the original gearshift, removed, and a gearshift handle at about a 90 degree angle, placed on instead, as the original gearshift resulted in hitting your hand on the lower console. The horn for his KITT, is also on the Gearshift.
I'll post the Link in a reply to this YouTube video.

You can find the gearshift part, at about
5:38 through the video.
