I have been looking around for an upgrade to my stock shifter **** and I have not been having any luck finding anything that I like that fits the 06', if anybody knows of some good online stores that have some good looking shifters that would be great!

 

Try UPR I put the billet pistol grip in mine.

 

these are pretty cool

From the UPR link:

"All Shift ***** listed above are for 79-04 Mustangs and all 12mm Threads !"

Does anyone know if the 06 Mustang shifters are 12mm, too?

 

Yes they are. I used one of theirs with no problem.
