keith.rose1 Posted March 7, 2020 Share Posted March 7, 2020 I recently obtained a 3.62 diff via Eb to change the gearing from the 3.9 one I had. When I came to fit new h shaft seals I found the normal 62mm dia didn't fit, it requires about 54mm. I then thought I would test to see if my half-shafts fitted ('92 De Dion C/flow) - they don't, they are too large a diameter. The diff in every other way looks like a normal 7 inch open diff - but what is it??I have solved the problem by getting another 2nd hand one, and went out for my first go with it today. I want to sell on the this seemingly odd diff, but can only honestly do that when I know what it is. Thoughts please!Keith Link to comment Share on other sites More sharing options...

Wrightpayne Posted March 8, 2020 Share Posted March 8, 2020 I bought a 3.6 diff off ebay, took to SPC to have my ATB fitted into it only to be told it wouldnt fit!External dimensions will be different if a 6.5. Link to comment Share on other sites More sharing options...
