Post subject:  Subaru 4.444 VLSD diff to Datsun 1600?

Hi guys I'm looking at a Subaru WRX diff with a 4.444 ratio I'm sure its a VLSD an looking to fit it into my Datsun 1600 which has a 240k diff.
what are the pro's an cons? does anyone have this set up already?

I know there are Subaru R160 Adapter Stubs available to suit the Datsun shafts,
but wanting to run the R180 (can import Stubs from the States)

the car particulars are its a 1970 Australian Assembled vehicle it is powered by a twin Weber fed cranky L20 from a Bluebird with a 5 speed box which is most likely from a 240k,
looking at for a fun zippy machine & not out to set land speed records.

knowing there is thousands of previous posts mentioning this from way back in 2008 stating the VLSD is evil an a pre 90's R200 would be the go.. after skimming though a Jillion posts already, rather cut straight to the point for my application. Thanks for the help in advance cheers!

Pretty sure the R180 stubs from US (and those available here) don't suit VLSD, they're made for the clutch plate type LSD's. VLSD need a unique stub with two different splines on the one shaft on one side.

R200 is big, heavy, expensive and overkill for an L-series powered 1600

I run a 4.44 R160, love the ratio. Its a bitza - open 4.44 from late Subaru fitted with clutch plate LSD from Subie RX turbo.

The later vlsds don't have the extra spline and have a smaller viscous pack that drives off the standard spline. Depending on how much lsd action you want (I suspect they won't give you much) it could be a good cheap solution.
But sounds like a clutch pack STi R180 and those stubs is more suitable for.you.
