I think I posted pics of that before where the guy was fitting one to an old Celica ?
Other option is a normal IRS rear diff, inverted. Same F/R
As far as I'm aware the 32/33 share the same ratio which is something like a 4.2, the R34 is in the high 3s I think. I'm using an R33 gearbox so either would do but obviously I need to think about the rear matching. I know they're integral to the sump, I have built a few but never measured the sump or cwp size. Your other option is in my mind too. I'd be interested to see how big a BMW X5 front diff is because that shares the same ratio as a Cossy!
Theres a Lambo Gayardo front diff on ebay for £1600
