You don't say what model, but you need a 3.64 (my choice), 3.73, or (boy racer choice) a 3.91.
These are all likely to come fitted in the larger 188 medium case diff., but will fit in place of your small case version with a small adjustment in prop. length, as long as the diff comes complete with output flanges.

The car is a j reg cabbie that started life as a 318. Would it be best to get a prop rather than adjust the length

kev on the props they have a slide adjuster on the middle of them you undo the big nut in the middle slide the rear secion of the prop out to the output flange of the diff then do the nut bk up its like a pinch sleeve the nut clamps the prop
