Hello,

Is there a LSD available for my 1.6 cortina mk 4/5 rear axle?

GTE.

I think Quaife do them for approx. £500.

I'd prefer someone else to confirm but I think it's the same diff as the capri 2.8i axles (think all the axles were "the same" apart from the width and the bits on the forging for the trailing arms on the cortina one.)

If so, get an LSD from a capri 2.8i special or Brooklands. I paid £200 for a complete axle with good plate LSD a couple of years ago.
