malibud Posted May 3, 2013 Share Posted May 3, 2013 I asked this on another forum and have searched around but have not gotten a straight answer . don't want the diff to get gone either so... Is this a direect bolt in to a 1970 240z - the diff. from a datsun 720 3.9 it has the bolt up flanges . seems like it would easier than getting all the parts for the r200 minus the weight thanks a bunch ..

BluDestiny Posted May 3, 2013 Share Posted May 3, 2013 720 front diffs are 4.11, It was a direct bolt in on my 280zx. You just need to use your stub flanges (the 720 uses CV axles I believe). Quote Link to comment Share on other sites More sharing options...
johnc Posted May 3, 2013 Share Posted May 3, 2013 720s front R180s can be 4.11 or 4.38. Some were rumored to be 3.90 but in 20+ years I've never seen one. Quote Link to comment Share on other sites More sharing options...
malibud Posted May 3, 2013 Author Share Posted May 3, 2013 We will see I was told it was 39/10 . from what I have read the beginning of 1983 till June were 3:9 I will let you know when it is in my hands Quote Link to comment Share on other sites More sharing options...
