WEL Posted December 22, 2020 Share Posted December 22, 2020 Can anyone tell me how many splines are on the Caterham driveshaft (for a Sierra diff). I've seen a diff but its for small 23 spline driveshafts.Thanks Link to comment Share on other sites More sharing options...
David_Long Posted December 22, 2020 Share Posted December 22, 2020 IIRC it is 26, but then I thought they were all the same on the 7 inch diff. Link to comment Share on other sites More sharing options...

Simon.Rogers Posted December 23, 2020 Share Posted December 23, 2020 There are small spline diffs out there.A very nice ebay chap pointed this out to me when I was collecting 3.14 ratios. Link to comment Share on other sites More sharing options...
Wrightpayne Posted December 23, 2020 Share Posted December 23, 2020 I found this which has pictures showing the external dimension differences which are quite subtle...https://passionford.com/forum/general-car-related-discussion/496829-ford-sierra-6-5-rear-diff.html Link to comment Share on other sites More sharing options...
