Early (1965) Ford open differential with a 3.9 ratio (crown 39 pinion 10) recently removed from my Lotus Elan S3 and in full working order. This will suit a Lotus 7 S3/S4 with with a Ford live axle, possibly also a very early Caterham 7. Also fits a wide range of other cars including Cortina, Anglia, Escort, Capri etc. No unusual noises, clonks, whine or oil leak from nose seal. Unknown mileage, but has covered 8k trouble free miles in my ownership over last 3 years. Removed in March only to replace with a longer ratio, for more relaxed cruise rpm. Please note this is for the diff only and does not include Ford axle casing or Elan diff carrier. I can supply a choice of two diff flanges to suit your prop-shaft. £150 ono. I am located in North Wales and price does not include carriage. Collection welcome or purchaser will need to arrange a courier. I can help with delivery for Manchester or West Midlands.
