Limited Slip help needed. I.D. and value??
 

I have a pair of these LSD's and I am not sure of the application. I suspect that they came from a IMSA racer in the 80's, but I have never see the 'male'splined output shafts like this.

The drive flange mates up with a 930 R/P.

Any input on application and value?

Thanks

David,

At first blush (without scale) I thought they are the 904 LSD that fits the 901 case.

If they take the larger 917 P/N friction discs, then they fit the 935 adaption of the 930 transmission. The splined axle parts mate with the Ti flanges that drive the big 935 axle assemblies – the Ti ones with the big rubber ‘doughnut’.

I think that, with the exception of the splined axle parts, these will also fit a type 911 and 915. Take one apart and measure and count the discs (two types). The ring gear bolt diameter should be 146 mm and the OD of the flange 170 mm.

Best,
Grady

Grady,
correct on the ring bolt diameter.

Here is a pic of the guts
