Telling the Zeal Functions apart..

[aeontony]

I searched for this stuff so much that my first inclination upon trying to post was to click "search", honestly.

I have a set of used Zeal Functions-the thing is I am not too sure how to tell the Function Basic and Function B6s apart. The problem is it appears the rotary dials on the pillow mounts have fallen off..I have a bolt coming out of the top. I am not sure if I can take a wrench and try to twist it one way or another to adjust the dampening. If it is adjustable, then I'd know it's a B6, if not, I may twist something off by accident.

My coilovers came without manuals or the perch wrench so I am kind of at a loss as to how to adjust this thing. The top is the dampening, I believe, but I also have something on the bottom (on the fronts), kind of a valve cap that comes off. The seller told me this was the dampening adjustment but I know he's not right. Am I supposed to take the valve off then adjust the bracket height somehow? Is that what the valve is for?

While I'm at it-does anyone know where I can go to purchase the four bolts that bolt the driveshaft to the differential? (online)

thanks for any answers!
