The 02Q transmissions are all the same on the other side (gear ratios are slightly different on some models) of the clutch housing including the case.
I'm using this Peloquins 4motion/Quattro diff to do the conversion.
I have a transfer case off of an 2012 Audi TT Quattro, but as far as I've researched, the transfer cases are largely the same between most of the Gen 4 Haldex transmissions.
You'll still need an AWD differential and the mounting bracket but not much else.
If you're interested in seeing more 4motion conversion stuff, feel free to check out my build thread.
I'll be posting up more pics of the transmission when we start that part of the build.
All this was already discussed in this thread. Malo has bolted the AWD differential on a FWD gearbox a long time ago. What is not mentioned here is, that VW has changed the ratio for almost all gears in the 4Motion gearboxes, so what you are building with bolting the AWD differential on a FWD tranny is not OEM. But it works.
The bracket what you are mentioning was also discussed, I presented it myself some time ago when I made the conversion. There it has to be checked if the engine has the mounting holes for it. Engines that VW has not used in 4Motion models might not have it.
He even says it in his post on page 2:
One thing I am sure about is transfer case has 2 input shafts: inner for right front axle and outer for rear differential. So the real question is if FWD tranny differential has this pre-diff outer output shaft for rear diff. I did not have time to research this.
