I am currently looking at purchasing a 90-93 D21 TD27t 5-speed Terrano and i am wondering if there are different transaxle codes stamped on the chassis tag to state if it has a rear limited slip diff or not?? Or is the only way to jack it up and give the wheels a spin??
I have noticed a lot of the Terranos out there seem to have open rear diffs which just ain't cool, may have to go for a welded up option

Any help would be much appreciated
Thanks.
