901 tranny and this ?? ZF limited slip?

Looking at this on ebay and wonder if it will fit my 914?

Very rare early Porsche ZF 901 limited slip differential for '64-'68 aluminum case transmission. Good shape but I have no idea what "slip" it's set at. Comes with matching axle flanges.

The only markings/numbers on the diff are:

4061 004 0041 435 848

Thanks
Josh

I'm fairly certain that you can convert your existing trans to limited slip with the parts from this transmission but, I don't think you can just use the transmission as-is. Since this is '64-'68 I'm assuming it was out of a 911. The problem is that the engine & trans in a 914 are in backwards and so if you just install this as-is you will have 5 reverse gears and 1 forward.

I'm not an expert but someone else here can chime in on this..................Vern

I haven't heard of an aluminum-case 901; I had assumed they were all magnesium like ours. However, our transmisison is a version of the 901 gearbox, so the ZF clutch-type limited slip for a 901 "should" work in a 914 gearbox.

I am not certain, though.

This LSD has the output for the old "universal Joint" coupling not the CV joint coupling. The LSD MIGHT work but you would have to get replacment output pieces. Gaurd Transmission may have them.

The early 901 ('65-'68) diff uses diff bearings with 45mm ID. The late 901 & 914 diff uses bearings with 50mm ID. This is one of the major areas where these two diffs "differ".
