WOW! I've been trying to find one of those. Glad someone is trying to revamp this idea. I read somewhere that manual N/As and SRTs were slightly different. It was a matter of millimetres, but still a PITA.
If you are planning to get these into production, and you are producing for LIMITEDs too, I'd definitely be interested.
I personally think the shifter does not need any CROSSFIRE lettering on it. The neater, the better...
Thumbs up to this idea. Post more pics as the project progresses.
