ST205 rear diff

OK, question of those who know more than me..

Did All ST205s (regardless of market) come with the rear torsen LSD?

Or was this an option?

And the ST205 and ST185 Torsen Rear diff are the same correct?

all had em if im not mistaken

All 205s had rear TORSEN and it's the same as the 185 homologation TORSENs.

Also, FYI you don't have to get different rear axle stubs, the difference between the 2 is just the clip on the end that holds them in.
Open diffs have a pull off clip [you remove the rear cover and pull the clip off of the stub] while TORSENs have a pop out clip like the front stubs [not sure if the front clips would work on the rears or not].
