While doing a search for Feroza LSD's I came accross a diff lapping site and on this site it listed many manufacturers and there diff types.
Here is the site
http://www.difflap.com.au/ratios/def.htm
Now the interesting thing to find out was what type of diff the Feroza has and it seems they are Hitachi Diffs. Anyway here is what is listed for the feroza
DAIHATSU 1994 FEROZA,H180,4X4, WAGON, 4CYL, LO, LSD Ratio: 7X37
DAIHATSU 11/92 FEROZA,R180,FRONT, 4X4,4 CYL,INDEPENDANT, FRONT, 1.6LT PETROL Ratio: 7X37
The interesting bit I have made red and from my Datsun days
(here he goes again) I know that a R180 is an Hitachi independant diff also come in R160 (smaller, 1600, or WRX), R180 (240z, 240K, 260z etc) R190 and R200 (300zx, skylines, silvias etc), the numbers represent the distance accross the diff (SIZE) or something so 160 is 160mm, 180 is 180mm etc and a H180 is of the same series as a bluebirdand the Bluebirds had H190's which would have to be similar. Also the Datsun 720 utes also had R180's at the front in different ratios as well.
I Do know the R series diffs are very Tuff, have seen plenty of R180's pushing out 250+hp at the wheels and last a long time so no wonder the feroza diffs are strong.
Anyway getting to my point is I know they make R180 LSD's

Thought this might be usefull
