Finally found it ... hahahaha ... thanks to you, evilshyt. Honestly the LSD u told me I have no idea whether it will fit to my car or not? but again, thanks to you have shown me the lsd parts. with $1195 price tag, I'm pretty sure thats the AE86 with Disc brake LSD which won't fit to my OZspec AE86.
Toyospares told me the LSD for aus spec AE86 only cost me $250 instead of $1000+
I'm not the one who bought the AE86 with race prepared carby engine.
