Short Shifter? Still have the stock unit?

[Perfectlap]

a few questions:

has anyone who installed a short shift kit still in possesion of the stock shift linkage? (or whatever you call it) Interested in selling it?
I see that there are cheap B&M knock offs on ebay for as little as $25, but I would rather stick with a stock unit.

2nd question:

Does anyone know if there is any difference between the 5 speed shift knob
and the six speed shift knob other than the graphic of the two different gate patterns on the top of the knob? In other words will a 5 speed shift knob fit on a 6 speed gear lever? and vice versa...

3rd question (for the 993 owners):
other than the boot being completely different, will a 986/996 shift knob work on a 993?
