Thanks for the info mate, I was expecting the manual shifter would sit a whole lot further back than that. I've attached a pic of where mine was midway through the build with a sr20 box/engine. Do you think an RB20/25 engine/box would be futher back or about the same?
I ended up turning my shifter around aswell and where it currently sits is no problem at all but any futher back and it will probably foul on the handbrake.
