I can take a picture, but it won't show much. I need a before pic. The M5 shifter is a little shorter than the 540i. I kept my 540i shift knob. I can't believe how easy the install was. If you are interested in doing this mod, buy a used Z3 M shifter because it is the same throw as the uuc shifter.
If you buy a 5 series, most of the guys on the m5board.com mod the hell out of their M5s. Which means they dump their OEM M5 stuff for cheap. That is how I have picked up my M5 shifter and M5 sway bars.
I just picked up a pre-vanos intake manifold off of a junked 94 740i for $50 from ebay. The pre-vanos intake manifold should have the same dimensions of the Dinan intake manifold for the 540i and the M5. Since I have the Dinan CAI, throttle bodies, mass flow meter, all I need is the intake manifold. Sure beats paying $1500 for the Dinan intake manifold. I will also buy the stage 5 Dinan software to supplement the intake.
Just rambling on.
