I just think you are wasting time looking for a ratio like that when you can find a great 3.9 LSD for good all round performance! (plenty on epray)

If you're going to one of the salt lakes mettings then maybe you could take a few different ratios and try different ratios each run. I'd assume you have a fair bit of time to change the diff between each run?
Good luck with it

a 3.54 is easy and almost low enough for what you are after, otherwise 1100$ will get you a 3.3 or like from kameari, see other post benZ i think?
for the gearsets only.
or a g/box with very tall 5th

Brabham, try Nissan part no.38100-N3405 which is a 3.154 ring and pinion set listed for an R200 in the Datsun Competition parts list. I very much doubt they would be avalible new, but try US sites, as they were sold there new. Dont waste your time with Nissan Aust, the US is the answer, if you want one.
Also try www.locost7.info/gearcalc.php and dial in your numbers, It will tell how many RPM you will need to do what speed in what gear, It will be up to you to get the power to pull the numbers!!!
If you can get hold of a DVD called 'Big white Dyno', done at Lake Gardiner in '04 it will show you how hard it will be....
If you look at the DLRA results not mant cars do 200MPH (320kmh) goooood luck.

How did you go with this Brabham? I'm after something around 3.00:1 for a R200 which seems impossible but no harm asking.

Dont try a CIG Welded centre, as you will never get the weight balance from one side to other, with the plates, and gobs of weld, etc, and at high tailshaft rpm ( useing a 0.75 fifth gear, engine, say 7000, tailshaft will be spinning at 9500 rpm !) a welded centre will vibrate the living crap out of the car.
A LSD if plates are really pre-loaded, will do it, but the inertia losees will be greater than a Spool
