First-Gen Quattro Questions

[Richard Hoffman]

I have a few questions about the first-gen Quattro system now that the 016 
transmission topic is more clear to me.
The first-gen quattro had open diffs all around, with lockable center and 
rear diffs.  They were both vaccuum actuated?  My 1990 CQ has Quattro-II, 
will I be able to modify it (in the center console) to use the Quattro-I 
system without too much work?  Is it as easy as simply changing the switch 
in the center console from a single push button to a turn-switch or maybe 2 
push buttons?  The actual tranny swap isn't the tough part here, just the 
actual operable parts inside.
Also, with regards to the general operation of Quattro-I: is it harmful to 
leave the center diff locked during normal driving?  I don't mean 
permanently, just say if it rains and roads are only moderately slippery.  
Or if I'm having a day at the track and want the preventative traction 
control of Quattro.  Are there any limits to how I should use the lockin 
diffs?
I'm so used to Quattro-II that I'm not sure how Quattro-I behaves and I'm 
really unsure of using a 4kq 016 transmission (which I can get for a dime a 
dozen) in this car.
Thanks guys!
