Member Jonathan Kay Posted January 15, 2018 Member Share Posted January 15, 2018 1600 or 1700 cc?Live axle or de Dion?Jonathan Link to comment Share on other sites More sharing options...
Tazio Posted January 15, 2018 Share Posted January 15, 2018 I would have thought live axle , maybe a bit early for a de dion? Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted January 15, 2018 Area Representative Share Posted January 15, 2018 Brian,I'd guess, if its a genuine BDR chassis, that it'll be a dedion car. In which case, it will be a 7" Ford Sierra diff (rather than the similar 7.5" fitted to Granada/Scorpio). Link to comment Share on other sites More sharing options...
eric Posted January 15, 2018 Share Posted January 15, 2018 a 2.8 i sierra but with a light exterior modification , to help it to fit Link to comment Share on other sites More sharing options...
Wrightpayne Posted January 15, 2018 Share Posted January 15, 2018 Can you post a picture - you'll have a definitive answer in 10 seconds flat!!Ian Link to comment Share on other sites More sharing options...
Area Representative Piers300 Posted January 15, 2018 Area Representative Share Posted January 15, 2018 My 1985 Super Sprint (sold 8/9 years ago)was the last Chassis number before the first De Dion. CC never offered me the option to have DD. My car was 4 speed live axle. So in 1985, both axle’s were available.Piers Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted January 15, 2018 Member Share Posted January 15, 2018 Yes, which is why I asked.Jonathan Link to comment Share on other sites More sharing options...

elie boone Posted January 16, 2018 Share Posted January 16, 2018 measure the PCD of the studs of the axle, 108mm is Ford, the Ital axle is 95,25mm, the Ital halfshaft has a nut to hold the hub, the Ford item is 1 piece Link to comment Share on other sites More sharing options...
brianrsutton Posted January 17, 2018 Author Share Posted January 17, 2018 Elie,thank you it is an Ital axle or what we had in Australia is a Morris Marina and I am sure that there is other Morris cars that I can source spares Link to comment Share on other sites More sharing options...
Wrightpayne Posted January 17, 2018 Share Posted January 17, 2018 In the uk, the Marina morphed into the Ital in the late 70s / early 80s. I know because dad had 3 marina's and one Ital. DUT690K, MEA808P, BFP708T and VNR161X. Funny, after that I cannot remember any of his reg plates. These are the cars learned my car mechanic skills - setting valve clearances, fitting points and timing them in, plug gapping, greasing prop shafts and suspension joints etc.I believe the Triumph herald used the same diff internals - CWP.Ian Link to comment Share on other sites More sharing options...
