I had to use different axles for this diff though.Well....what I think... it is a R160. It would use the same axle seal IMO. And axle seal for a '00 Impreza L would be the same as an axle seal on a '00 Impreza RS. A VLSD doesn't make it any different on the seal.
Yes you had to use different axles, but your rear R160 axle stubs are not as THICK as my R180 STi axles. The lengths are different yes, but the thickness IMO may not be at all. I MAY be wrong becaus I don't have a JDM R160 LSD axle, but that's just what "I think."I had to use different axles for this diff though.
