Hi guys. My clutch just went out in my 86 ea82 dr. Looking on Orielys Web site there's 3 different clutches for an 86 ea82. Obviously I don't need the one for a 2wd, but the other 2 have me stumped.

The first one says the disk is 8 7/8" diameter, 21 spline, with a 7/8" input shaft.

The second one says the disk is 8 7/8" diameter, 24 spline, with a 1" input shaft.

I haven't torn the car apart yet or else I'd be able to tell.

You want the 225mm  (8 7/8"),  24 spline, 1" shaft.   Call it 225mm x 24T x 1".

The 225 x 21T x 7/8" is for an 83+ EA81 4spd

Perfect, thank you.
